“…Several correlations between the glacial stratigraphy of Tasmania and New Zealand and South America have been suggested (Kiernan, 1980(Kiernan, , 1983a(Kiernan, , 1985Colhoun, 1985a). However, many of these correlations are unreliable and do not demonstrate temporal correspondence.…”

Mapping, analysis and interpretation of glacigenic sediments in the King Valley, Tasmania has led to a revision of the Pleistocene stratigraphy of Tasmania. The sediments provide evidence of a glaciation that occurred between the Middle Pleistocene Henty Glaciation and the Early Pleistocene Linda Glaciation. The Moore Glaciation is estimated, on the basis of weathering rinds, amino-acid dating and palaeomagnetism to have occurred between 400000 and 550000 yrs BP. At Baxter Rivulet, sediments of the Moore Glaciation rest unconformably on highly weathered till and weathered Ordovician limestone and are overlain by outwash gravel of the Henty Glaciation. The Moore Glaciation sediments can be divided into four formations on the basis of lithology, organic content and degree of chemical weathering. The Huxley Formation (oldest) was deposited by an ice advance of the Mt. Jukes Glacier and is overlain by the Baxter Formation. The Baxter Formation consists ofa bed of organic silty sand which records a cool non-forested flora of an interstadial period. The overlying Pyramid and Moore formations are outwash gravels from the Mt. Jukes and King Valley glaciers respectively. Though deposited during the same general ice advance, these two gravels were deposited at different times and show that the glaciers of the West Coast Range had spatially differentiated responses to climatic change.

“…This texture contrasts with the typically clastic* cave sediments of more temperate regions (e.g., Farrand 1975;Goldberg 1979;Kiernan 1983), and greatly aids sampling for micromorphology. Thin-section sample preparation followed routine procedures described in Lee and Kemp (1994).…”

This is the first detailed study of the micromorphology of archaeologically important cave sediments in the Great Cave of Niah, in the humid tropics of Sarawak, Borneo. Micromorphology is used to describe the sediments and post-depositional alteration, reconstruct the palaeoenvironments, and refine the environmental history of late Pleistocene deposits associated with the human remains (the so-called Deep Skull dated to ca. 43,000-42,000 B.P.). Micromorphology provides details of the shape, roundedness, arrangement, and chemistry of grains, aggregates, precipitates, and sedimentary structures that make up the cave sediments. The dominant processes in the West Mouth of the Great Cave of Niah are guano sedimentation, fluvial and shallow pond deposition interrupted by desiccation, mass movement, and chemical weathering. Also important is post-depositional alteration by bioturbation, mineral translocation and reprecipitation, and diagenesis. Micromorphology also provides evidence for short periods of soil development, burnt surfaces, and deposition of small fragments of bone within the sediment. Together this information indicates the fine details of the environment occupied by humans, the scale and effects of the mass movement processes that deformed the beds in which the human remains are preserved, and the taphonomic processes that reworked and redistributed archaeological material within this part of the cave.

“…In the King Valley, its tributary the Nelson Valley, and adjacent parts of the central West Coast Range, three principal drift formations have been recognised some of which may represent more than one episode of glaciation (Kiernan, 1980(Kiernan, , 1983bColhoun, 1985;S. Fitzsimons, pen.…”

Part of an extensive ice cap that developed in the Tasmanian Central Highlands during the late Cainozoic discharged southwards into the valley of the Franklin River and its upper tributaries where it merged with smaller glaciers that accumulated behind local snowfences. Glacial landforms and sediments in the now heavily forested valleys indicate that at least three and possibly as many as six glaciations took place. The earliest and most extensive glaciation occurred during the Pliocene or earliest Pleistocene. At this time ice extended at least 27km down the Franklin Valley and covered at least 326km2 of the study area. This ice was confluent with glaciers in the West Coast Range to the west and in the Derwent Valley to the east Such confluence offers the possibility of better correlation of glacial events between western Tasmania and the Central Highlands. The smallest and most recent glaciation occurred during the late Last Glacial Stage when the Franklin Glacier did not exceed 12km in length. The glaciers were characterised by high rates of mass throughput and were of temperate maritime type.
