Updates to this cadastre in 2012 will be released on the following dates: January 15 and 29 - February 12 and 26 - March 11 and 25 - April 8 and 22 - May 6 and 20 - June 3 and 17 - July 1, 15 and 29 August 12 and 26 - September 9 and 23 - October 7 and 21 - November 4 and 18 - December 2, 16 and 30. In 2013 the 1st release date will be January 13.

  • The digital dataset combines data from the Oracle ozchron, sites, and rocks tables and is presented as shapefiles and mapinfo files for the rubidium-strontium, conventional uranium-lead and samarium-neodymium geochronology themes. This dataset package will eventually include the uranium-lead shrimp data, and is intended to be updated on a regular basis until the project is completed.

  • The surface geology of Queensland ranges in age from Palaeoproterozoic to Recent. The oldest rocks largely occur in the Mount Isa and Georgetown Inliers in the northwest and central north of the state respectively. These rocks have undergone greenschist to amphibolite facies metamorphism and were extensively intruded by granite during the Mesoproterozoic. Metamorphics of Meso to Neoproterozoic age occur in the Coen Inlier in eastern Cape York, in the Hughenden-Charters Towers-Townsville region to the south and east of Georgetown, and also further south in the Anakie Inlier. During Cambrian to Ordovician times, extensive carbonate dominated, marine sedimentation took place in the Georgina Basin, West and southwest of Mount Isa. These rocks were subsequently faulted and gently folded prior to the Devonian, perhaps during the mid-Ordovician Thompson Orogeny. Silurian to Devonian marine sedimentation is preserved in the Hodgkinson and Broken River Basins in the north east of the state while similar aged, arc related deposits accumulated in the New England Orogen which occupies a 200 km wide coastal strip between Bowen and Brisbane in the southeast of the State. The Hodgkinson - Georgetown region and New England Orogen were extensively intruded by granite during Carboniferous to Permian times. Permian to Triassic sediments of the Galilee and Bowen Basins outcrop in the central east of the state while similar aged sediments accumulated to the east and southeast within the New England Orogen. Widespread sedimentation during the Jurassic to Cretaceous (Carpentaria, Eromanga, Mulgildie, Surat, and Laura Basins) blanketed large areas of older bedrock, particularly in the central, southern and south western parts of the state. Finally, Cainozoic cover units comprise approximately half the surface geology with sand plain (Czs), sand plain with dunes (Czd), colluvium (Qrc), alluvium (Qa), and Tertiary to Quaternary basalt flows comprising the major components. The data set was initially compiled from older regional data sets including those covering the Eromanga, Surat and Carpentaria-Karumba Basins. Extensive areas were recompiled using more recent 1:250 000 and 1:100 000 scale mapping, particularly in the Georgetown-Charters Towers-Ebagoola region, and also the area of the New England Orogen. The data set includes nearly 1800 named, informal or unnamed units.

  • The "Surface geology of Australia 1:1 000 000 scale, Victoria, 2nd edition" dataset is modified from the 1:1 000 000 scale "Victoria 1:1 000 000 Geology" map published in 1999 by the Geological Survey of Victoria. Modifications are mainly in the classification of all granitoid intrusions which were previously unnamed, and in the classification of Cainozoic regolith stratigraphy. The 1999 Victorian state data has been merged with the 1:1 000 000 "Geology of the Murray Basin" (BMR, 1991) dataset, primarily to achieve consistency in units across the Murray Basin in Victoria, South Australia and New South Wales. The geology of Victoria consists of a wide range of sedimentary, igneous and some metamorphic rocks. The oldest rocks are Cambrian clastic sedimentary rocks in the Glenelg River area, and greenstones along Moyston, Avoca, Heathcote and Governor faults. Most Cambrian rocks are metamorphosed to low-medium grade. The Middle(?) Cambrian Nargoon Group consists of the Glenthompson Sandstone and undated and undifferentiated metasedimentary rocks between the Yarramyljup and Escondida faults in western Victoria. The Late Cambrian St Arnaud Group and interpreted lateral equivalents, including marine turbiditic sandstone, mudstone, and shale, crop out between the Moyston and Avoca faults in the western part of the state. The Ordovician Castlemaine Supergroup, which occurs mostly between the Avoca and Heathcote faults in central-western Victoria, is a sequence of marine turbiditic sandstone, mudstone, black shale, and minor granule conglomerate. These rocks host the important Bendigo-Ballarat gold fields. Ordovician sediments in northeast Victoria (northeast of the Governor Fault) consist of the turbiditic sequences of the Adaminaby, Bendoc, and Kiandra groups. Silurian to middle Devonian clastic sedimentation in central Victoria between the Avoca and Governor faults is represented by the very thick Murridindi Supergroup of mainly siltstone and sandstone. Conglomerate is a minor component, and limestone rare. Late Silurian to Early Devonian clastic sediments and limestones occur in scattered outcrop areas in eastern Victoria (e.g., Wentworth, Barmouth, Mt Tambo, Buchan, and Errinundra groups). Devonian felsic volcanic rocks occur across the state. Some Cambrian and Ordovician granitic rocks are mapped in western Victoria in the Glenelg River area. Silurian granitic rocks occur in the east of the state and Early Devonian granitic rocks occur east of the Governor Fault and west of the Heathcote Fault. Middle to Late Devonian granitic rocks occur mainly in central Victoria. Much of the Late Devonian Avon Supergroup of clastic sedimentary rocks outcrop in central-east Victoria, although some occur in far east of the state. Some early Carboniferous clastic sediments (e.g., the Boorhaman Conglomerate) occur in the northeast of the state. Permian clastic sediments such as the Wild Duck Formation and equivalents, comprising glaciomarine and fluvial diamictite, sandstone, mudstone and conglomerate, occur in central and western Victoria. The Triassic Mt Leinster Igneous Complex of granite, syenite, trachyte and volcaniclastic sediments are found in northeast Victoria. Jurassic trachyte lavas, (e.g. the Coleraine Trachyte), occur in far west of the state. The Cretaceous Otway Group of fluvial volcaniclastic arkosic sandstone and mudstone occurs in the southern part of the state and extends offshore into Bass Strait. Palaeocene to Oligocene basaltic lavas and associated pyroclastics and fluvial sediments (Older Volcanics) occur in scattered outcrop areas in the southwest part of the state, while Holocene to Miocene lavas flows and cinder cones (Newer Volcanics) occur in large areas of the southwest part of the state.
