Department of Geology, Eduardo Mondlane University, PO Box 257, Maputo, Mozambique ([email protected]) Temperature, pressure and time are the main causes for coalification. However, time is considered to have effect on coalification only when temperatures are sufficiently high to speed up chemical reactions, i.e., the higher the temperature, the greater the influence of time. The treatment of 5154 data on World coals from more than 150 coal basins and 145 coal fields carried out during this study shows that for coals of all Eras (Palaeozoic, Mesozoic and Cenozoic) and facies (Gondwana, North Atlantic) the dominant coal rank is bituminous, specially sub-bituminous, irrespective of the deposition and dynamo- thermal conditions. When particular periods and regions are considered, there are some exceptions to this general trend. For instance, Quaternary coals are dominated by peat. In South America Cenozoic coals are predominantly sub-bituminous, and in Gondwana Asia Cenozoic coals are mainly lignites. European coals of Mesozoic and Cenozoic ages are mainly sub-bituminous, although Cenozoic bituminous coals occur almost with the same frequency as the sub-bituminous coals. The amount of heat necessary to provoke coalification up to the bituminous stage is relatively low. On the other hand, during this stage, organic matter deposits are characterized by high fluid contents and by H-bonds in the molecular structures of their components. Both fluids and H-bonds give the system a greater thermal conductivity and heat circulation efficiency, as well as a greater penetrability throughout the basin, allowing thus an “easy” coalification up to the bituminous stage. At this stage, coal goes through a chemical stability due to the loss of the above mentioned properties. Heat circulation faces a resistance justified by the enrichment of carbon content, which is known to be thermo-isolator. The spatial distribution of heat varies gradually towards the heat source, the most significant heat-effects being near the source. Thence the tendency of anthracite to form near the heat sources but with a short extension as a consequence, as stated before, of the short distance reached by heat due to the poor thermal conductivity of coal in the bituminous stage, and to the chemical stability that characterizes this rank stage. In other words, it looks like coal faces a relatively dynamo-chemical and dynamo-thermal facility to reach the bituminous stage, and a strong resistance to go beyond this stage. Being so, great amount of coals will stay in the range of bituminous coals. 7 th Patras 2005: 57 Annual

    1 Revision 2 2 K-Bentonites: A Review 3 Warren D. Huff 4 Department of Geology, University of Cincinnati, Cincinnati, OH 45221 USA 5 Email: [email protected] 6 Keywords: K-bentonite, bentonite, tephra, explosive volcanism, volcanic ash 7 Abstract 8 Pyroclastic material in the form of altered volcanic ash or tephra has been reported and described 9 from one or more stratigraphic units from the Proterozoic to the Tertiary. This altered tephra, 10 variously called bentonite or K-bentonite or tonstein depending on the degree of alteration and 11 chemical composition, is often linked to large explosive volcanic eruptions that have occurred 12 repeatedly in the past. K-bentonite and bentonite layers are the key components of a larger group of 13 altered tephras that are useful for stratigraphic correlation and for interpreting the geodynamic 14 evolution of our planet. Bentonites generally form by diagenetic or hydrothermal alteration under 15 the influence of fluids with high Mg content and that leach alkali elements. Smectite composition is 16 partly controlled by parent rock chemistry. Studies have shown that K-bentonites often display 17 variations in layer charge and mixed-layer clay ratios and that these correlate with physical 18 properties and diagenetic history. The following is a review of known K-bentonite and related 19 occurrences of altered tephra throughout the time scale from Precambrian to Cenozoic. 20 Introduction 21 Volcanic eruptions are often, although by no means always, associated with a profuse output 22 of fine pyroclastic material, tephra. Tephra is a term used to describe all of the solid material 23 produced from a volcano during an eruption (Thorarinsson, 1944).

There are three types of kaolinite rocks in the present research area: the first type (be called tonsteins) occurs in the roofs, partings and floors of coal seams, normally called tonsteins, which are thinner and widespread; the second type, usually 2~6 m thick, is not adjacent to coal seams, usually in the lower part of coal measures of Upper Permian, similar to the flint clay in North America; the third type is soft kaolin clay of 0.5~5 m in thickness and associated with surficial weathered coals. Results of XRD, IR, DTA and SEM studies show that the content of kaolinite minerals is in general more than 70% and up to 90%~100% in some good quality rocks. The elements of Mo, W, Zr, Hf, Th, Ag and Sb are very rich in kaolinite rocks in the study area, with their average contents being higher than those in the earth`s crust, basalt and granite.

  • 7 Siliciclstic Sediments II: Mudrocks
    7 Siliciclastic sediments II: Mudrocks 7.1 Introduction Mudrocks are the most abundant type of sedimentary rocks, constituting about 45-55% of the sedimentary sequences. But since they are easily weathered, they are covered with vegetation and are poorly exposed. Mudrocks can be deposited in all sedimentary environments, but the majority are deposited in river floodplains, lakes, large deltas, the more distal areas of clastic shelves, basin slopes, and deep sea floors. The main constituents of mudrocks are the clay minerals and silt-grade quartz. In terms of grain size, clay refers to particles less than 4 µm in diameter, whereas silt is between 4 and 62 µm. On the other hand, clay as a mineral is a hydrous aluminosilicate with a specific sheet structure (to be discussed below). The term mud (also lutite) loosely refers to a mixture of clay- and silt-grade material. The mudstone, the indurated or lithified equivalent of mud, is a blocky, non-fissile rock, whereas shale is usually laminated and fissile (fissility is the ability of rock to split into thin sheets). Argillite is used for more indurated mudrock and slate is the metamorphic mudrock possessing a cleavage. Claystone is the sedimentary rock consisting of a clay- grade material. Siltstone consists of more silt-grade particles than clay. Calcareous mudrocks are called marls. Fig. 7.1 gives a scheme for mixed sand-silt-clay deposits. 1 Fig. 7.1: Classification of siliciclastic sediments based on sand, silt and clay content. In the field, the terms mudstone, shale, claystone and siltstone are best qualified by attributes referring to color, degree of fissility, sedimentary structures, and mineral, organic and fossil content (Tab.

    Age constraint for the Moreno Hill Formation (Zuni Basin) by CA-TIMS and LA-ICP-MS detrital zircon geochronology Charl D. Cilliers1, Ryan T. Tucker1, James L. Crowley2 and Lindsay E. Zanno3,4 1 Department of Earth Sciences, Faculty of Science, Stellenbosch University, Stellenbosch, Western Cape, South Africa 2 Department of Geosciences, Boise State University, Boise, ID, USA 3 Paleontology, North Carolina Museum of Natural Sciences, Raleigh, NC, USA 4 Department of Biological Sciences, North Carolina State University, Raleigh, NC, USA ABSTRACT The “mid-Cretaceous” (~125–80 Ma) was punctuated by major plate-tectonic upheavals resulting in widespread volcanism, mountain-building, eustatic sea-level changes, and climatic shifts that together had a profound impact on terrestrial biotic assemblages. Paleontological evidence suggests terrestrial ecosystems underwent a major restructuring during this interval, yet the pace and pattern are poorly constrained. Current impediments to piecing together the geologic and biological history of the “mid-Cretaceous” include a relative paucity of terrestrial outcrop stemming from this time interval, coupled with a historical understudy of fragmentary strata. In the Western Interior of North America, sedimentary strata of the Turonian–Santonian stages are emerging as key sources of data for refining the timing of ecosystem transformation during the transition from the late-Early to early-Late Cretaceous. In particular, the Moreno Hill Formation (Zuni Basin, New Mexico) is especially important for detailing

    1.1 Volcanogenic Tonsteins from Bukit Asam Coalfield, South Sumatra Basin, Indonesia Ferian Anggara1*, Amanda A. Sahri2, Zain A. N. Asa2, D. Hendra Amijaya1 1Geological Engineering Department, Gadjah Mada University, Yogyakarta 52884, Indonesia 2Undergraduate program Geological Engineering Department, Gadjah Mada University, Yogyakarta 52884, Indonesia *Corresponding Address: [email protected] In the Muara Enim Formation, at least 18 coal layers are found, however only five main coal seams layer in Bukit Asam coalfield e.g the A1 and A2 (Mangus) seams, B1 and B2 (Suban) seams as well as C (Petai) seams are considered economic to be mined. A major influence on the evolution of peat mires and coal formation in the Muara Enim Formation was volcanic activity during the deposition. Volcanic eruptions in the surrounding area produced ash which accumulated as claystone layers or tonsteins in the coal seams. Based on systematic field mapping, several tonsteins layers were founded and sampled in the research area, e.g. tonsteins in interseam layer of A1, A2, B1, B2 and C seam. This paper only focused on the tonstein in between B and C seam. The mineralogy of the tonsteins has been evaluated using thin section and qualitative X-ray diffraction (XRD) techniques. Tonstein in Bukit Asam coalfield, consisting mainly of kaolinite, quartz, dickite and calcite. The results suggest that these tonsteins were derived from acid volcanic ash fallout, which was subsequently altered into relatively kaolinitic rocks through hydrolysis and diagenesis in a peat-bog environment. The tonsteins in Muara Enim Formation are significance in providing distinctive horizons for stratigraphic correlation purposes.

    TONSTEINSAND BENTONITES IN NORTHEAST BRITISH COLUMBIA (930.P, 1) By W. E. Kilby INTRODUCTION Tonsteins are presently considered themost reliable coal seam correlationtool amilable (Stack, et ai., 1982). Such ancient volcanic ash bands in coal-bearing and adjacent strata of northeastern British Colum- bia were examined during the 1983 field season as the preliminary phase of a study documenting ther,e time lines throughout the coalfield. Altered ash bands also were noted and studied by pr'evious workers; Stott (19681, Duff and Gilchrist (19831, and Spears and Duff (in pressj, In this paper the terms tonstein and bentonite will be used to broadly group all the types of altered volcanic ash encountered, Tonsteins have a distinct tuffaceous texture and are confined, in this study, to the coal- bearing formations, Bentonites, on the other hand, are generally restricted to marine formations and have the greasy feel and conchoidal fracturingcommon to bentonite.Montmorillonite-illite and mixed- layer (smectite) group clay minerals are more prominent in the bentonites; kaolinite is the major com- ponent of both groups (see accompanying table). Generally, a particular band is consistently a tonr:tein or a bentonitethroughout the studied area, but exceptionsexist and arevery significant,Tonsteins and bentonites examined in this study are the alteration products of volcanic ash. Controversy over the origin of these materials has continued for decades but the last 10 yearshas seen a general acceptance of their volcanic origin (Stack, et a/,, 1982). It will beseen that the only plausible explanation for many of the intervals studied here is that they represent volcanic ash.
