  • Water Management in the Anthony–Pieman Hydropower Scheme
    Water management in the Anthony–Pieman hydropower scheme Pieman Sustainability Review June 2015 FACT SHEET Background The Anthony–Pieman hydropower scheme provides a highly valued and reliable source of electricity. The total water storage of the hydropower scheme is 512 gigalitres and the average annual generation is 2367 gigawatt hours. Construction of the Anthony–Pieman hydropower scheme has resulted in creation of water storages (lakes) and alterations to the natural flow of existing rivers and streams. The Pieman Sustainability Review is a review of operational, social and environmental aspects of the Anthony–Pieman hydropower scheme that are influenced by Hydro Tasmania. This fact sheet elaborates on water management issues presented in the summary report, available at http://www.hydro.com.au/pieman-sustainability-review Water storage levels in the Anthony–Pieman Water levels have been monitored at these storages since hydropower scheme their creation in stages between 1981 and 1991. The Anthony–Pieman hydropower scheme includes eight Headwater storages: Lake Mackintosh and Lake water storages, classified as headwater storages (Lakes Murchison Mackintosh and Murchison), diversion storages (Lakes Lakes Mackintosh and Murchison are the main headwater Henty and Newton and White Spur Pond) and run-of-river storages for the Anthony–Pieman hydropower scheme. storages (Lakes Rosebery, Plimsoll and Pieman). Lakes The water level fluctuates over the entire operating range Murchison, Henty and Newton and White Spur Pond do not from Normal Minimum Operating Level (NMOL) to Full release water directly to a power station; rather they are Supply Level (FSL) (Figures 1, 2). used to transfer water to other storages within the scheme.

During the Late Wisconsin, icecap and outlet glacier systems developed on the West Coast Range and on the Central Plateau ofTasmania. Local cirque and valley glaciers occurred in many other mountain areas of southwestern Tasmania. Criteria are outlined that enable Late Wisconsin and older glacial landforms and deposits to be distinguished. Radiocarbon dates show Late Wisconsin ice developed after 26-25 ka BP, attained its maximum extent c. 19 ka BP, and disappeared from the highest cirques before 10 ka BP. Important Late Wisconsin age glacial landforms and deposits of the West Coast Range, north-central and south-central Tasmania are described. Late Wisconsin ice was less extensive than ice formed during middle and earlier Pleistocene glaciations. Late Wisconsin snowline altitudes, glaciological conditions and palaeodimatic conditions are outlined. Key Words: glaciation, Tasmania, Late Wisconsin, snowline altitude, palaeoclimate.

  • The Geology, Geochemistry and Structure of the Mount Darwin - South Darwin Peak Area, Western Tasmania
    The Geology, Geochemistry and Structure of the Mount Darwin - South Darwin Peak Area, Western Tasmania. by Andrew Thomas Jones B.App.Sci.(RMIT) A thesis submitted in partial fulfihnent of the requirements for the degree ofBachelor of Science with Honours. CE:-iTRE FOR ORE DEPOSIT A:"/D EXPLORATION STUDIES Geology Department, University ofTasmania, November 1993. Abstract The Cambrian Darwin Granite intrudes calc-alkaline rhyolites of the Central Volcanic Complex on the Darwin Plateau, western Tasmania. Two distinct granite phases are recognised, an equigranular granite and a granodiorite. A biotite grade contact aureole is preserved in the Central Volcanic Complex immediate to the Darwin Granite. Debris flow deposits of volcaniclastic conglomerates and sandstones, and coherent dacite lavas of the Mid - Late Cambrian Tyndall Group unconformably overlie the Darwin Granite and Central Volcanic Complex, and are in turn overlain unconformably by pebble to boulder conglomerates of the siliciclastic Owen Conglomerate. Stratigraphic and structural evidence recognise three deformation periods within the Mt Darwin - South Darwin Peak area: the Mid - Late Cambrian, Late Cambrian - Early Ordovician, and the Devonian Tabberabberan Orogeny. Mid - Late Cambrian deformation, evidenced by granitic and foliated volcanic clasts in basal Tyndall Group conglomerate, indicates catastrophic uplift and subsequent unroofing of the granite prior to Tyndall Group deposition. This unconformity represents a significant Cambrian hiatus in the southern Mount Read Volcanics. A second unconformit)r between the Tyndall Group and the Owen Conglomerate marks cessation of Tyndall Group deposition with the onset of deposition of large volumes of siliceous detritus. The two Devonian Tabberabberan-related deformations are characterised by, NW and N­ trending dextral strike slip faulting and locally intense N-trending cleavage development.

  • Geochemistry of Darwin Glass and Target Rocks from Darwin Crater, Tasmania, Australia
    Meteoritics & Planetary Science 43, Nr 3, 479–496 (2008) AUTHOR’S Abstract available online at http://meteoritics.org PROOF Geochemistry of Darwin glass and target rocks from Darwin crater, Tasmania, Australia Kieren T. HOWARD School of Earth Sciences, University of Tasmania, Hobart, Tasmania 7000, Australia Present address: Impacts and Astromaterials Research Centre, Department of Mineralogy, The Natural History Museum, Cromwell Road, London SW7 5BD, UK Corresponding author. E-mail: [email protected] (Received 1 March 2007; revision accepted 25 July 2007) Abstract–Darwin glass formed about 800,000 years ago in western Tasmania, Australia. Target rocks at Darwin crater are quartzites and slates (Siluro-Devonian, Eldon Group). Analyses show 2 groups of glass, Average group 1 is composed of: SiO2 (85%), Al2O3 (7.3%), TiO2 (0.05%), FeO (2.2%), MgO (0.9%), and K2O (1.8%). Group 2 has lower average SiO2 (81.1%) and higher average Al2O3 (8.2%). Group 2 is enriched in FeO (+1.5%), MgO (+1.3%) and Ni, Co, and Cr. Average Ni (416 ppm), Co (31 ppm), and Cr (162 ppm) in group 2 are beyond the range of sedimentary rocks. Glass and target rocks have concordant REE patterns (La/Lu = 5.9–10; Eu/Eu* = 0.55–0.65) and overlapping trace element abundances. 87Sr/86Sr ratios for the glasses (0.80778–0.81605) fall in the range (0.76481–1.1212) defined by the rock samples. ε-Nd results range from −13.57 to −15.86. Nd model ages range from 1.2–1.9 Ga (CHUR) and the glasses (1.2–1.5 Ga) fall within the range defined by the target samples.

  • Interim Management Plan for the Mt Read RAP
    Tasmanian Geological Survey Tasmania Record 1997/04 Interim Management Plan for the Mt Read RAP A Co-operatively Formulated Plan by Government Agencies, Statutory Bodies and Relevant Land Users for the Mt Read RAP SUMMARY The formulation of this plan by a co-operative committee, comprising representatives from Government Agencies, statutory bodies and relevant land users, is a ‘first’ for Tasmania. The effort by these various parties with an interest in the Mt Read area demonstrates the commitment to protect the area in the absence of any formal reserve. The Mt Read RAP is almost entirely covered by two current mining leases, ML7M/91 over the Henty gold deposit and ML28M/93 associated with the Rosebery silver-lead-zinc mine, and exploration licence EL5/96 held by Renison Limited. The RAP is within the Mt Read Strategic Prospectivity Zone, which means that if the status of the land is changed and this effectively prevents activities on the current mining tenements, then compensation may be payable. The vegetation around Lake Johnston is acknowledged as having exceptionally high conservation and scientific values, which is why a management plan for the area was written in 1992 and adopted by the lessee. There is a need to expand the scope of the previous plan so that all users of the Mt Read area are aware of the need to abide by measures to protect the vegetation. In addition, media reports have generated much interest in the ancient stands of Huon pine growing in one part of the Mt Read RAP. Studies indicate that the existing Huon pine on the site comprises one or a few individuals which may have vegetatively reproduced on the site since the last glaciation.

  • DRAFT Tasmanian Inland Recreational Fishery Management Plan 2018-28
    DRAFT Tasmanian Inland Recreational Fishery Management Plan 2018-28 DRAFT Tasmanian Inland Recreational Fishery Management Plan 2018-28 Minister’s message It is my pleasure to release the Draft Tasmanian Inland Recreational Fishery Management Plan 2018-28 as the guiding document for the Inland Fisheries Service in managing this valuable resource on behalf of all Tasmanians for the next 10 years. The plan creates opportunities for anglers, improves access, ensures sustainability and encourages participation. Tasmania’s tradition with trout fishing spans over 150 years. It is enjoyed by local and visiting anglers in the beautiful surrounds of our State. Recreational fishing is a pastime and an industry; it supports regional economies providing jobs in associated businesses and tourism enterprises. A sustainable trout fishery ensures ongoing benefits to anglers and the community as a whole. To achieve sustainable fisheries we need careful management of our trout stocks, the natural values that support them and measures to protect them from diseases and pest fish. This plan simplifies regulations where possible by grouping fisheries whilst maintaining trout stocks for the future. Engagement and agreements with land owners and water managers will increase access and opportunities for anglers. The Tasmanian fishery caters for anglers of all skill levels and fishing interests. This plan helps build a fishery that provides for the diversity of anglers and the reasons they choose to fish.

Acid drainage from abandoned mines in Tasmania Dr Shivaraj Gurung FOREWORD Acid drainage, resulting from the oxidation of sulphide-bearing rocks, is recognised as one of the major sources of heavy metal pollution in many of waterways proximal to metal mining sites in Tasmania. Prior to this investigation, only limited information was available on the extent of acid drainage impact from historic abandoned mine sites. Section 37.5 of the Tasmanian State Policy on Water Quality Management (1997) requires that “an inventory of sources of acid drainage from historic mine workings should be carried out”. This reconnaissance investigation provides a basis for this inventory. The program is a component of the proposed State Water Quality and Quantity programs and was largely funded by the National Heritage Trust. Water analyses were carried out by the Department of Primary Industries, Water and Environment at the Analytical Service Tasmania laboratory. Geochemical analyses, map production and project management were carried out by Mineral Resources Tasmania. This report primarily focuses on acid drainage from abandoned mine sites in Tasmania. It presents new data and the compilation of existing data on water chemistry and geochemistry associated with abandoned mine sites in Tasmania. The report accompanies a series of acid drainage impact maps and an inventory of acid-producing abandoned mine sites.

A. MAHMUD,1* S. NASEEM,2 M. HALL1 and KHALID A. ALMALKI3 1School of Earth, Atmosphere and Environment, Monash University, Clayton, VIC 3800, Australia 2Department of Geology, University of Karachi, Pakistan 3King Abdulaziz City for Science and Technology, Saudi Arabia (Received March 3, 2015; Accepted November 5, 2015) A geochemical study of the Late Cambrian-Early Ordovician sandstones exposed in the West Coast Range, Tasmania, Australia, was carried out to develop an understanding of the provenance and tectonic settings. The average composition of these sandstones displayed high SiO2 (92.72%), moderate Al2O3 (3.34%) and Fe2O3 (1.71%), low K2O (0.90%) and MgO (0.15%), and very low CaO and Na2O (<0.01%) concentrations. The sandstones were mainly classified as quartzarenite, and some samples were classified as sublitharenite. Tectonic discrimination diagrams based on major and trace elements suggest passive margin settings. Provenance diagram (Al2O3 vs. TiO2) revealed that the Owen Group was derived from a silica-rich source. The average chemical index of alteration (CIA) was 78.45, indicating that the source area suffered severe weathering due to persistent warm and humid climate. High amounts of rare earth elements (REE) and strong negative anomalies on the chondrite-normalized REE pattern indicate an oxidizing deposition environment. The trace element chemostratigraphy reflects sharp contrasts in concentrations, distinguishing the unconformity between the lower and upper sequences and also shows the effect of alteration assemblages.
