CONCLUSIONS MAGNETIC METASEDIMENTS AS A To make full use of aeromagnetic data, it is necessary to STRATIGRAPHIC MARKER WITHIN SUNDOWN understand the geological controls on the magnetic GROUP materials, primarily magnetite. In the Monuments area the observation that bedding trends in some outcrops are On outcrop scale, magnetite concentrations in the Sundown oblique to the trend of the aeromagnetic anomaly led to Group metasediments of the Monuments area are bedding early erroneous interpretations that magnetite was parallel, and folded by F2 folds. There is a good case to epigenetic and emplaced in shear zones. investigate the use of magnetic metasediments as a Detailed geological mapping and ground magnetics stratigraphic marker within the Sundown Group. showed that magnetite concentrations are parallel to bedding, Within the metasediments of the Monuments grid, it has and that the folded magnetic beds are sliced up and strung out not been possible so far to delineate a structural form surface. along the north-easterly trend of the high temperature shears, This is because no distinctive marker horizon has been producing the observed aeromagnetic anomaly.

MURRAY BASIN MAPPING PROGRESS The semi-arid Booligal map sheet area in the Riverine Plain has a shallow basement prospective for volcanogenic related mineralisation in the east and a central unexplored possible structural basin of Devonian sediments - the Booligal Trough.

GEOLOGY Overlying the basement rocks are several fluvial to The Booligal 1:250 000 map sheet area lies immediately lacustrine units of Tertiary age. These are the Olney Formation west of Hillston in New South Wales. It is a flat, semi-arid of the Renmark Group (which can be subdivided into three region, dominated by interacting Quaternary intervals) and the Calivil Formation. A minor unit, the morphostratigraphic units (figure 16). The study area is Pooncarie Ironstone, may also be present, but has not been almost entirely covered with unconsolidated and mapped in the Booligal area. There are two aquifer-bearing consolidated sediments of the Murray Basin, and the depositional sequences within this Tertiary succession. The basement consists for the greatest part of Lachlan Fold older consists ofthe concealed basal fluvio-Iacustrine Middle Belt rocks. This area lies within the eastern part of the Eocene to Late Miocene Olney Formation of the Renmark Murray Basin and consists offluvial and possibly marginal Group. A Late Tertiary depositional hiatus underlies the marine Tertiary sedimentary units deposited in an second (overlying) sequence, which consists of subsurface intracratonic setting. Sedimentary thicknesses vary from sands and sandstones of the Pliocene to Early Pleistocene 20 m to 200 m overlying basement highs and from 200 m fluvial Calivil Formation. Included within this second sequence to 410 m within basement troughs. The basement comprises is the Shepparton Formation, in addition to Early to mid pre-Tertiary sequences, especially Lachlan Fold Belt rocks Quaternary fluvial deposits. and intrusions. The formerly interacting Quaternary morphostratigraphic Basement rocks crop out in three areas: the Warranary units of fluvial, aeolian, and lacustrine depositional systems Range; Trida; and Caning anima Hill. The Warranary Range are now largely inactive. The areally dominant fluvial systems forms a topographic basin, U-shaped in plan, with the axial are mapped as either Coonambidgal Formation or Shepparton plane oriented north-west-south-east.
