From introduction: The Tasman Geosyncline covers the eastern part of the continent of Australia, an area of over 2 million km'. The area has been a major source of Australian gold and tin production, and though it contains important base metal sulphide deposits, these are overshadowed in scale by the very large stratabound Proterozoic deposits (for example, Mt Isa, Broken Hill and McArthur River). This dissertation deals with the metallic mineral deposits of the Tasman Geosyncline, and as such does not include the extensive post Palaeozoic continental successions, with their important coal reserves, that overlie the deformed geosyncl i nal sequences.

This thesis examines the history of Tasmania’s national parks and protected areas from 1885-2005, analysing the interests, and the organisations and individuals representing them, which have influenced outcomes. Significant organisations representing different and sometimes competing interests have been community based groups, chiefly the naturalist and scientific bodies, bushwalking clubs and environmental organisations; tourism associations, industry interests, notably forestry, mining and hydro-electricity, federal, local and state governments and government agencies, notably the National Parks and Wildlife Service. The thesis argues that the establishment and development of Tasmania’s national parks and protected areas have been shaped by the negotiations, accommodations, conflicts and shifting relative power among these competing interests. In the late nineteenth and early twentieth centuries consensus of interest among Tasmania’s social and political elite facilitated the declaration of Tasmania’s first scenery reserves and national parks. Conflicts of interest between preserving land in its natural state and industrial development grew apparent from the 1920s however, and Tasmanian governments managed park expansion through politics of compromise in which national parks accommodated industry demands. The environment movement that emerged in the 1960s protested national parks’ ‘residual’ status and with federal government support defeated the State government’s plan to build a dam within an area proposed for a Wild Rivers National Park. Following environmentalists’ success in over-riding State government processes to expand the State’s national park estate and World Heritage Area in the early 1980s; the State government strengthened its direct control over the National Parks and Wildlife Service and focused its attention on national parks’ tourism role. Aspects of tourism in national parks are, however, incompatible with the preservation of environmental and wilderness values, which resulted in further political conflict between government-supported tourism interests and the national parks movement. This thesis complements earlier research on Tasmanian national park history by Mosley, Castles, Shackel, Mendel and Cubit by extending analysis of that history to the twenty-first century, examining the role of the National Parks and Wildlife Service in that history since the agency’s inception in 1971, and addressing both environmental and social perspectives of national park history. It concludes that by the twenty-first century Tasmanian national park policy required a framework of social values associated with national parks in which to situate environmental protection as national parks’ primary purpose.

The Lower Parmeener Supergroup consists of 500 to 900 metres of marine and terrigenous sedimentary rocks, deposited in the high-latitude Tasmania Basin during the late Carboniferous to middle Permian, at the end of the late Paleozoic ice age. Two bioclastic carbonate units, the Darlington and Berriedale limestones, are of particular interest due to their formation in this polar, cold-water environment. Both limestones contain ice-rafted debris scattered throughout, signifying numerous icebergs, and are under- and over-lain by glendonitic siltstone indicating near-freezing seawater. Despite the unusual environment, seawater in the Permian Tasmania Basin was, with the exception of an anomalously high 13C value, isotopically and chemically similar to modern seawater. These limestones consist of a high-abundance, low-diversity heterozoan assemblage, dominated by large, robust brachiopods, bryozoans, and Eurydesma bivalves. Sponge spicules and crinoids are locally important constituents. The carbonates are interpreted to have been deposited in mid-shelf environments during sea-level highstands, where the faunal communities were beyond the depths of grounding icebergs, and sufficiently outboard from terrigenous sediment influx and brackish water. Growth and preservation of biogenic carbonates were promoted by up-welling of nutrient-rich water, which sustained high levels of primary productivity in the water column and phosphate concentrations in the sediment. Lower Parmeener Supergroup carbonates were exposed to a complex series of diagenetic processes, commencing on the seafloor and continuing during rapid burial. Limestone composition was further modified by diagenetic fluids associated with the intrusion of Mesozoic igneous rocks. Alteration in the marine paleoenvironment was both destructive and constructive; although dissolution took place there was also coeval precipitation of fibrous calcite cement, phosphate, and glauconite. These processes are interpreted to have been promoted by mixing of marine waters and enabled by microbial degradation of organic matter. In contrast, meteoric diagenesis was insignificant, being confined to minor dissolution and localized cementation, although mechanical compaction was ubiquitous. Chemical compaction was instigated at burial to depths of approximately 150 m, and promoted extensive precipitation of ferroan calcite. Diagenesis may well have ended here, except for the subsequent intrusion of massive Mesozoic diabases and associated injection of silicifying fluids into the limestones. Finally, fractures associated with Cretaceous uplift were filled with late-stage non-ferroan calcite cement. / Thesis (Ph.D, Geological Sciences & Geological Engineering) -- Queen's University, 2008-04-23 11:12:58.461 / NSERC

Separated from mainland Australia by the Bass Strait, Tasmania has acted as an island preserve maintaining large populations of many mammalian species presently uncommon, rare, or extinct on mainland Australia. There are few studies of Tasmanian mammal distributions. Recent distributional maps, based on information from surveys and mammal specimens, allowed for an investigation of the species density distributions of the terrestrial mammals of Tasmania. Compilation of species' distributional information into species density distributions provides an overview as to which areas may provide the most significant habitat for the greatest number of species; what geographic variations may influence species distributions; and which regions remain least surveyed for mammalian species in Tasmania.
