Map Catalogue Database (Mineral Resources Tasmania)
공공데이터포털
Catalogue of published geoscience maps produced by Mineral Resources Tasmania. Map themes include geology, engineering geology, land stability and geohazards, mineral deposits, groundwater resources, and geophysics. Maps have been produced at various scales ranging from statewide maps to more detailed regional mapping. The map catalogue can be searched and map images downloaded on the MRT website https://www.mrt.tas.gov.au/products/database_searches/map_catalogue or more popular maps and map series are listed in the MRT Publication List https://www.mrt.tas.gov.au/__data/assets/pdf_file/0005/229640/Price_list_v2.2.pdf
1:250,000 Geology Data and Maps (Mineral Resources Tasmania)
공공데이터포털
Geological lines (contacts, faults, linears), geological rock units, and structure data derived from 1:50,000 and 1:63,360 Digital Geological Atlas printed map series and 1:25,000 digital geology data where available. Geological units and boundaries have been generalised and compiled for 1:250,000 scale. The digital data is available as a seamless state wide coverage and is used to produce the Digital Geological Atlas 1:250,000 Scale map series.
Mineral Occurrences Data (Mineral Resources Tasmania)
공공데이터포털
Mineral occurrences, including operating and abandoned mines, located in Tasmania, with summary mineral occurrence data, derived from the Mineral Occurrence Database, which is a component of the Tasmanian Information on Geoscience and Exploration Resources (TIGER) system; administered by Mineral Resources Tasmania (MRT). Mineral occurrences include operating and abandoned mines, prospects, mapped occurrences and mineral fields or mineralised areas. Mineral occurrences are shown subdivided by commodity type, which largely corresponds to the mineral categories defined in the Mineral Resources Development Act 1995; Fuel Minerals, including geothermal (Categories 2, 4 and 6), Construction Minerals (Category 3), Industrial minerals (Category 5) and metallic minerals (Category 1). Alluvial, placer and man-made (tailings dam) occurrences are shown separately (commodities are mineral Categories 1 and 5) and occurrences (generally abandoned mine workings) where there are no records of the commodity of interest, are shown as unknown. The summary Mineral Occurrence data includes: the Mineral occurrence name (note that an occurrence may have multiple names or aliases), the commodity type (as defined above), the nature of the occurrence (e.g., mine or prospect, mineralised area), the commodity or commodities present, the geological unit that hosts the occurrence and the positional accuracy of the record. A Details field provides a link to a Mineral Occurrence Details page where further information, including references and public domain resource figures, may be available.
Exploration Licence Data (Mineral Resources Tasmania)
공공데이터포털
Current Exploration Licence polygons (including applications and exploration release areas) across Tasmania, with tenement information derived from the Tasmanian Information on Geoscience and Exploration Resources (TIGER) system; administered by Mineral Resources Tasmania (MRT), Department of State Growth. Exploration licence polygons delineate areas in which licence holders are permitted to explore for the listed categories of minerals: Category 1: metallic minerals and atomic substances; Category 2: coal, peat, lignite, oil shale and coal seam gas; Category 3: rock, stone, gravel, sand and clay used in construction, bricks and ceramics; Category 4: petroleum products except oil shale; Category 5: industrial minerals, precious stones, semi-precious stones; Category 6: any geothermal substance. Exploration licences may be granted over both Crown and private land, so long as that land falls under the Mineral Resources Development Act 1995. Mineral exploration activities may include: geological, geophysical and geochemical surveys, drilling, and taking samples of rock, soil, water or other substances for analysis. Mining is not an exploration activity and cannot occur on an exploration licence.
