CHAPTER 11

SUMMARY AND CONCLUSIONS

1) The Gunnedah Basin is a structural trough forming the middle part of the larger Sydney-Bowen Basin. It occupies a foreland posifion between the New England Fold Belt (orogen) and the Lachlan Fold Belt (craton). The foreland configuration began to fonn after the mid-Permian period of deformafion in the New England Fold Belt. The foreland basin setfing largely conceals older morphotectonic features which have an origin related to deep-seated stmctures within the upper crust and have infiuenced the tectonic (and consequently depositional) development of fhe basin throughout its history.

• The basin consists of several lineariy arranged troughs defined by bounding longitudinal and transverse ridges and highs. The structure and geometry of the basement, together with the distribution and type of the Eariy Permian sedimentary basin fill and the associafion with widespread volcanic rocks are consistent with volcanic rift models. Inifiafion of the basin was by surficial extension along a shallowly dipping normal detachment fault underiying fault blocks defined by normal listric faults. The fault blocks rotated and subsided to form a half-graben rift valley in the eariiest Permian. Subsidence of the half-grabens formed rift compartments which were infilled by rift-stage sediments.

• The Meandarra Gravity Ridge played a significant role in understanding the origin and formafion of the basin. The ridge represents a significant zone of inhomogeneity in the upper cmst caused by deep-seated dense mafic intrusions. Over much of its length, the Meandarra Gravity Ridge is laterally displaced by low gravity transverse trends, spaced 35 to 90 kilometres apart. There is a striking correspondence between the high gravity anomalies and the trough areas which contain the thickest sedimentary pile (and hence maximum subsidence), and also between fhe low gravity transverse trends and the mapped transverse structural highs in the basin.

• The lateral displacements (discontinuities) of the Meandarra Gravity Ridge represent transfer (transverse) structures which were active during rifting and thus bound rift compartments of varying size and subsequent thermal subsidence histories. The discontinuities are interpreted to have been infiuenced by thick basal volcanic sequences of relafively lower density than the large high-density mafic source underiying the basin in the upper crust.

• There is a remarkable correspondence between the discontinuities in the Meandarra Gravity Ridge and the structural highs; this together with the linear arrangement of the troughs in a persistent north-north-westeriy trend, enabled prediction of basement structure within areas of litfie or no borehole control and provided the basis for subdivision of the Mullaley and Gilgandra Sub-basins into structural subunits. It also enabled prediction of basement faults which have little or no surface 498 GUNNEDAH BASIN - SUMMARY AND CONCLUSIONS

expression, such as the Boggabri Fault and Rocky Glen Fault. Tadros (1988c) invoked the Rocky Glen Fault as a shallow low angle thrust fault to explain the offset between the centres of the troughs in the Mullaley Sub-basin and the maxima of the positive anomalies of the Meandarra Gravity Ridge. The evidence for this fault has been recently provided by Korsch et al. (1993) from the deep seismic refiection profile across the basin through Boggabri. Scheibner (1993b) has already adopted and incorporated the new structural subdivision of the Gunnedah Basin, presented in this thesis, in his new structural map of New South Wales and in his synthesis of the geology of the state in Memoir Geology 13 (Scheibner in prep.).

2) The volcanic rift/extensional mechanism of basin fonnation produced major structural elements that influenced sedimentafion over the entire history of the basin. However, that infiuence was modified and complicated by the superimposition of the subsequent foreland tectonic regime in the Late Permian and Triassic.

• During the Eariy Permian, transverse and longitudinal structures effectively controlled and confined sedimentafion to the trough areas (overiying the half-grabens). In the Late Permian and Triassic, longitudinal stmctures were periodically reactivated as thrust faults resulting in uplift and erosion of much of the upper Permian sequence particulariy in the Maules Creek Sub-basin and the northern Mullaley Sub-basin. The transverse structures acted as growth features with a remarkable influence on development, distribufion and geometry of deposifional systems, their component facies and the contained coal, as well as on emplacement and distribution of igneous intrusions and extrusions.

• The basement structural elements also controlled the distribution of igneous intrusions and volcanism. Late Carboniferous to Eariy Permian eruptions followed transfer faults and fioored the developing Gunnedah Basin with basalt, while silicic volcanism appears to have developed parallel to the basin margins along longitudinal extension/detachment faults. Younger phases of igneous activity (Jurassic Ganrawilla Volcanics and Tertiary volcanic complexes of the Nandewar, Warmmbungle and Liverpool Ranges) followed reacfivafion of major transfer faults.

• Thermal relaxation followed cessation of the extension in the latest Eariy Permian to eariiest Late Permian and caused basin-wide subsidence and widespread marine transgression. Although the marine transgression provided a wider coverage for the sediments of the Porcupine and Watermark Formations than the restricted deposition of the Eariy Permian sediments, the infiuence of subsidence in the trough areas was still significant.

3) The change to foreland tectonics provided a new source of volcanic-lithic detritus for the basin carried by westeriy and south-westeriy trending mixed-load streams from the overthrusted New England Fold Belt region. Although totally covered by the marine sediments, the transverse structures continued to infiuence deposition of the overiying sediments during the foreland basin stage by acting as relatively positive features characterised by less net subsidence than the adjacent trough areas. 11. SUMMARY AND CONCLUSIONS 499

• Although foreland loading of the thmst belt in the New England orogen was the dominant cause of subsidence during deposifion of the Black Jack Group, the inherent volcanic rift-related basement structural elements had a significant effect by varying the subsidence rates in the different basin compartments and subsequently on clasfic sedimentafion and peat accumulafion.

• Thus, recognifion and mapping of basement structures and understanding of the basin's tectonic history highlighted the interrelafionship between basin origin, tectonics and sedimentation and provided a framework for sedimentological and strafigraphic analysis and coal resource evaluafion.

4) The integrated hierarchical approach to genefic stratigraphic analysis of Galloway and Hobday (1983a) has been applied to the study of the Gunnedah Basin sequence in general (presented in (Tadros 1993b) and the upper Black Jack sequence for this study, in particular. The analysis included definifion of the geometry and distribution of genefic stratigraphic units and mapping sediment dispersion patterns within the sequence, and thus provided the means to develop sedimentafion models and to determine the palaeogeography and tectonism expressed as basin subsidence and uplift in the source regions.

• Lithofacies maps for the upper Black Jack sequence show a pattern of sand bodies which emphasise structurally controlled dominant fluvial character with a major axial tmnk channel complex fed by easteriy and westeriy contributory channels.

• The upper Black Jack sequence has been divided into four major genefic elements; the Hoskissons Peat-swamp, the Lacustrine, the Western Fluvial and the Eastern Fluvial Systems based on contrasts in lithology, deposifional and tectonic setting, on palaeogeographic relationships and on recognition of coal seams of regional extent as major genefic sequence boundaries.

• The depositional systems served as mapping units with bounding surt^aces for the contained genefic facies and allowed establishment and or refinement of coal seam correlafions, particulariy for those of subregional extent. Mapping the deposifional systems and the contained facies provided the means to construct the Late Permian depositional and tectonic history ofthe basin.

• The genetically defined units provided the basis for the establishment of the new formal lithostrafigraphy for the Gunnedah Basin. The new stratigraphy encompasses not only the upper part of the Permian sequence but the entire Permo-Triassic Gunnedah Basin sedimentary fill. The author applied his intimate and detailed knowledge of the basin's geology, and ufilised results of sedimentological analysis available on different sections of the Gunnedah Basin fill, to develop the new strafigraphy. The expanded knowledge of the Gunnedah Basin sequence also allowed correlation, not only of its stratigraphy but also of its deposifional history, with those of the Sydney Basin.

• The Permian stratigraphy section has been ratified by the Coalfield Geology Council of New South Wales. The new Gunnedah Basin stratigraphy is now widely used by workers from the coal, petroleum explorafion and mining industries and from universifies. The detailed formal definifion of the Gunnedah Basin lithostratigraphy including the comprehensive correlafions with the Sydney 500 GUNNEDAH BASIN - SUMMARY AND CONCLUSIONS

Basin have been brought fonward and presented in chapter 2 in this thesis to provide the proper stratigraphic framework and terminology for the succeeding chapters.

5) The Hoskissons Coal and the newly recognised and defined Breeza Coal Member are regionally extensive, have tectonic and time significance and serve as genefic sequence boundaries. These seams separate genefic sequences of disfinctly different deposifional setfings, bedding architecture, and sediment composition. The basin-wide accumulation of the Hoskissons peat represents a significant period characterised by almost total non-deposifion of terrigenous elastics and marks a change in basin depositional history from predominantly deltaic and shallow marine sedimentafion to fiuvial and lacustrine condifions ofthe upper Black Jack depositional episodes., divides the upper Black Jack secfion into an underiying lacustrine and dominanfiy bed-load fluvial complex (the Western Deposifional Episode) that had its source from the Lachlan Fold Belt in the west and an overiying mixed load fluvial and alluvial fan system (the Eastem Depositional Episode) derived from the New England Fold Belt.

• Coal seams of subregional extent, although not representing sequence boundaries, have fime significance locally and are useful in finer subdivision within the larger genetic strafigraphic packages. Detailed lithofacies mapping of the interseam sediments provided the means to reconstruct the evolution of the upper part of the Black Jack fiuvial systems, enhanced recognition of depocentres, revealed areal and stratigraphic distribution of sand bodies within the genefic units and ulfimately allowed recognition ofthe impact of basement structures on sand distribution.

6) The Hoskissons Coal, is the product of the Hoskissons Peat-swamp System and consists predominanfiy of vitrinite-poor, inertinite-rich coal with higher liptinite content than in most Australian coals. Temporal variations are represented by an upward decrease of vitrinite content in the lower secfion of the coal and by an upward increase in the upper section with a corresponding increase in the amount of disseminated and discrete mineral matter. Liptinite (mainly sporinite) content increases towards the top where alginite is also present.

• The Lacustrine System displays cyclic alternation between upward-coarsening sediments of lake margin facies and organic-rich mudstone of lake basin facies.

• Principal components of the Western Fluvial System interpreted from drill core are channel fill, channel margin and fioodplain/ floodbasin facies. Architectural element analysis of an outcrop at Mount Watermark indicated that the sandstone was deposited by discrete, broad, probably shallow, low sinuosity channels comparable with Models 9 and 10 of Miall (1985) for low sinuosity rivers, and the middle-upper Brownstones of Allen (1983). In vertical profile, the sequence combines features characteristic of low sinuosity rivers of the "Piatt type" and the "South Saskatchewan type", or its ancient analogue - the Battery Point Formafion.

• The Eastern Fluvial System consists mainly of channel fill, channel margin and fioodplain facies. Axial and tributary channel fill deposits have been recognised in drill core, with volcanic-lithic 11. SUMMARY AND CONCLUSIONS 501

conglomerate being the dominant lithology. Carbonaceous sediments, thick stony coals and tuff form an integral part of the fiood plain facies.

7) The Hoskissons peat accumulation followed rapid lowering of sea level after deposition of the Arkarula Shallow-marine System and the establishment of terrestrial conditions which lasted for the remaining part of the Late Permian and the Triassic. The upward decrease then increase in vitrinite content indicate a gradual fall and subsequent rise in the water table during peat accumulation. The presence of detrital inertodetrinite and desmocollinite associated with high mineral matter in the top plies suggests an hypautochthonous origin. The increase in the lipfinite content towards the top of the coal suggests that the peat in the upper parts fonmed under non-oxidising acidic condifions.

• Sediment and tectonic loading caused regional subsidence, termination of peat accumulation and establishment of lacustrine conditions in the eastern part of the basin. The presence of alginite at or near the top of the coal supports the change to lacustrine conditions which drowned the peat and prevailed in the eastern half of the Mullaley Sub-basin. Stmctural readjustment along the eastern edge of the cratonic Lachlan Fold Belt caused uplift (forebulge) and shedding of quartzose detritus of the Western Fluvial System. The lake was subsequently infilled by sediments of the Western Fluvial System that expanded through the confiuence of east-fiowing tributaries and a south-flowing axial channel complex. This was followed by regional peat accumulation of the Breeza Coal Member prior to renewed tectonic acfivity in the New England Fold Belt and the introducfion of coarse volcanic-lithic detritus of the Eastern Fluvial System to the axial drainage via southwest- flowing tributaries. Fluvial incision of the underiying Western Fluvial and Lacustrine Systems and sediment intermixing are evident in the main channel complex and the main tributaries. Influx of coarse detritus from the New England Fold Belt and westward movement of the basin axis caused south-westward migrafion of the axial drainage complex.

• Widespread silicic volcanism in the New England Fold Belt region contributed large amounts of pyroclastic detritus to the basin-fill. A major phase of lateral compression and thrusting of the New England Fold Belt onto the craton caused structural readjustment and uplift, particulariy in the north, and ended Permian deposition in the basin.

8) Depositional setfing had a significant infiuence on quality and confinuity of the Hoskissons Coal. The coal overiies nearshore, barrier beach and lagoon deposits in the south and centre ofthe basin, and overiies, and interfingers with, fluvial sandstone in the north and west, and deltaic facies in the south-east. Shoreline sands, formed to the south, protected the peat swamps from inundafion by the sea and kept the water table high enough to produce vitrinite-rich plies, low in mineral matter and sulphur, at the base of the seam. Raw and washed coal isoash trends show a dominant influence of the fiuvial setting on coal quality. Geographic zonation of the Si02/Al203 mole rafios of the coal ash corresponds closely with regional trends in the associated depositional systems. In the northern and south-western parts of the basin, the quartz-rich sediments of the Westem Fluvial System intertlnger with, and overiie, the coal which is high in discrete and disseminated mineral matter; both are silica-rich and of predominantly detrital sedimentary origin. The mineral matter in 502 GUNNEDAH BASIN - SUMMARY AND CONCLUSIONS

the east is clay-rich (low to medium SiOj/AljOg mole ratios) indicating tectonic stability and minor infiux of clay-rich sediments from the New England Fold Belt region. Secondary silica contributed to the medium to high SiOj/AljOg mole ratios in the northern and some of the eastern parts of the basin where tuff layers are interbedded within the Hoskissons Coal.

• Subsidence controlled the Hoskissons peat-swamp development, coal quality and thickness. Rate of subsidence was uneven across the basin and was structurally controlled. Organic-rich mudstone and "canneloid" coal formed in rapidly subsiding areas in the centre. Lowest rates of subsidence in the west and south-west produced a thin seam and exposed the coal to some degradation and partial erosion. Favourable subsidence rates in the north produced thick, vitrinite-rich top plies.

• Subsidence rate, and consequently coal quality and thickness, was infiuenced by compaction of the underiying platform of marine sediments or of the peat, superimposed by basement control. Differenfial compacfion of the underiying platform is based on a relationship between high sand percentage in the Arkarula Shallow-marine System and low-ash coal in the seam. The sand-rich areas apparently subsided at a rate at which the growth and accumulation of peat could be maintained. The sand-poor areas subsided more rapidly, outpaced peat growth and led to the development of broad depressions and infiux detrital material, resulting in increased concentrations of discrete mineral matter. Localised compaction ofthe peat (initiated by overbank fiooding) was, in some areas, independent of compaction of the underiying platform, and created shallow transitory lakes. Accumulafion of sediments within these lakes contributed to the discrete stone and tuffaceous layers in the upper section of the Hoskissons Coal, particulariy in the northern part of the basin. In the deeper parts of the transitory lakes, intermixing of fine silt and clay with degraded organic matter produced organic-rich mudstone and "canneloid" coals.

• Many of the eariy major structural elements of the basement in the Gunnedah Basin were active during sedimentation and had ulfimate control on all other factors which infiuenced subsidence, sedimentation and peat accumulation. There is a remarkable relationship between the Hoskissons Coal lithotype profile, quality and thickness and basement structural elements. Total thickness and number of major plies are greatest in the trough areas. Top plies are absent in areas where the Hoskissons Coal grades rapidly into lacustrine deposits in the trough areas. The basal ply thins out or is absent over transverse basement structural highs.

• The six coal seams, which have been recognised, correlated and formally defined, above the Hoskissons Coal in the upper part of the Black Jack Group, were also strongly influenced by their deposifional setfing. Peat accumulated in interchannel areas adjacent to the axial channel complex and principal tributaries. Locafion of the axial channel complex was largely structurally controlled and occupied the areas of maximum basin subsidence. Moderate subsidence rates in the north of the sub-basin tended to entrench the axial channel complex while in the south and south-east more rapid subsidence rates allowed greater lateral shift through aggradation and avulsion. 11. SUMMARY AND CONCLUSIONS 503

. Differenfial subsidence resulted in contrasfing coal-forming conditions. In the north, condifions of peat accumulafion within interchannel areas isolated by the axial and tributary streams were independent of neighbouring peat swamp systems and coal seam characteristics are difficult to correlate across the fluvial axes. Seams are fewer in number and generally thinner in the north due to the moderate subsidence rates, and many seams are characterised by abundance of tuff and tuffaceous sediments. Rapid subsidence in the south favoured thick widespread peat accumulafion except where the swamp has been disrupted by sediment influx from neartsy channels.

9) The knowledge gained from the comprehensive analysis of the stmcture and sedimentafion in the Gunnedah Basin, complemented with a study of the peat swamp environment and coal facies analysis, greatly improved understanding of the factors which controlled peat swamp development and peat formation, coal quality and distribufion, seam thickness and splitfing, and nature of the mineral matter in the coal, and provided the basis for reliable seam correlations. All of these are important factors in the assessment of the basin's coal resources, which are estimated at 29 billion tonnes of potentially usable in situ coal. The Black Jack Group contains the vast majority of that resource, and neariy half of the total resource is contained in the Hoskissons seam. Generally, the Hoskissons seam consists of a low sulphur, medium-ash, high-volatile, low to non-swelling coal. A coking fraction with moderate ash and swell characteristics can be obtained from a basal working section, which economically is the most important. A considerable proportion of the mineral matter in the Hoskissons seam is present as discrete sediment layers that can be easily separated by washing the coal to CF 1.60 RD leaving relafively cleaner coal at acceptable yields.

• The remaining coal resources are contained mainly in the six seams overiying the Hoskissons Coal. Although most of these seams extend over much of the south-eastern part of the basin, their best potential is mainly within the Caroona area, except in areas near the axial channel complex where quality deteriorates and in some cases the seam is split or replaced by fiuvial channel deposits.

• In general, these seams contain medium to high ash, medium volatile thermal coal of low to moderate swell. In addition, the lower seams, including the Caroona, Howes Hill and Breeza seams, have moderate coking potenfial; and the upper seams, including the Clift, Springfield and Doona seams, have low coking potential.

10) Exploration in the basin has concentrated on the Breeza, Caroona, West Gunnedah and Narrabri areas within the potentially economic zone of shallow (<500 metres), good quality coal in the east, where borehole spacing is between 4 and 8 kilometres or less and seam correlations are well established, allowing the coal resources to be calculated to Inferred status.

11) Although, the Hoskissons and the overiying seams approach the surt^ace over a significant part of the four potential mining areas, the geological characteristics, particulariy structure and igneous intrusions, and the physiographic features, such as topography, alluvium and flood plains, have interacted to minimise the open cut mining potenfial of the basin. The bulk of the resource is, therefore, amenable to underground mining methods only. 504 GUNNEDAH BASIN - SUMMARY AND CONCLUSIONS
