Clermont 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

Geochronology and related aspects of acid volcanics, associated granites, and other Proterozoic rocks in The Granites-Tanami region, northwestern Australia

Isotopic ages of Proterozoic acid volcanics and associated granitic intrusions in the northeast and southwest part of The Granites-Tanami region are reported and discussed. In the northwest, within The Granites-Tanami Block, the Mount Winnecke Formation, which includes acid volcanics that were probably erupted underwater, is intruded and weakly metamorphosed by the high-level Winnecke Granophyre. The acid volcanics and intrusives have similar major element compositions, and this, together with the field evidence, indicates that they are probably comagmatic. Rb-Sr total rock and mineral data for the Winnecke Granophyre yield an isochron indicating an age of 1802 Â± 15 m.y. and an initial Sr87/Sr86 of 0.7074 Â± 0.0036. Isotopic data for the lavas of the Mount Winnecke Formation give a preferred age of 1808 Â± 15 m.y. and an initial Sr87 /Sr86 of 0.7052 Â± 0.0038. In the southwest, at the western extremity of the Arunta Block, another acid volcanic suite, belonging to the Pollock Hills Formation, is intruded and weakly metamorphosed by the Mount Webb Granite. As in the northeast, the volcanics and intrusives have similar major element compositions, and are considered to be comagmatic. Combining Rb-Sr isotopic data from both the volcanics and intrusives yields an isochron indicating an age of 1526 Â± 25 m.y. and an initial Sr87/Sr86 of 0.711 Â± 0.004. These rocks are appreciably younger than those in the northeast. The acid igneous rocks in the southwest also postdate three other newly dated granitic units in The Granites-Tanami Block - the Lewis Granite, 1720 Â± 8 m.y.; the Slatey Creek Granite, 1770 Â± 55 m.y.; and The Granites Granite, 1780 Â± 24 m.y. - and are younger than the Gardiner Sandstone, the basal unit of the Birrindudu Group, which unconformably overlies The Granites-Tanami Block. K-Ar and Rb-Sr ages determined on glauconite from the Gardiner Sandstone show little consistency, due evidently to partial loss of radiogenic daughter products, but a preferred K-Ar age of 1560 Â± 20 m.y. is considered a reasonable minimum estimate for the age of sedimentation and diagenesis in the unit.

Devil's Creek, WA, 1999 (P1081), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Devil's Creek, WA, 1999 survey were acquired in 1999 by the WA Government, and consisted of 3935 line-kilometres of data at 300m line spacing and 70m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Formation of the Lord Howe Rise continental ribbon during eastern Gondwana breakup from multi-channel seismic reflection data

The Lord Howe Rise continental ribbon, offshore eastern Australia, formed during the Late Cretaceous rifting of eastern Gondwana. This project focuses on multi-channel seismic reflection and bathymetry data collected on a multi-leg marine geophysical survey in 2016 to constrain the nature of rifting and the formation of the Lord Howe Rise. We present processed pre-stack depth-migrated seismic reflection images and interpretations of a regional, ~900 km long east¿west-oriented profile at 27.2°S, from the oceanic Tasman Basin to the extended continental crust of the Lord Howe Rise. We find that the Tasman Basin contains buried basins that may be related to early transform faulting. The Tasman Basin has a sharp eastern boundary against the Dampier Ridge, within which are multiple rift basins up to 3 km deep. These basins are similar to those found on the Lord Howe Rise. The Middleton Basin separates the Dampier Ridge and the Lord Howe Rise and is a broad, well-stratified sedimentary basin of up to ~3.5 km thickness. This basin contains an unconformity that separates strata conformable with the basement and post-rifting strata. Both syn-rift and post-rift sedimentary sequences are found on the Lord Howe Rise. To better understand these rifting events, we present grids of pre-stack time-migrated seismic reflection lines covering two rift basins of the Lord Howe Rise. The two basins show contrasting evolution, including variations in normal faulting within the syn-rift sequences. These results help constrain the dynamic processes that caused the formation of the Lord Howe Rise continental ribbon.

Darwin Harbour Habitat Mapping Program: Northern Territory coastline

This resource contains a Northern Territory coastline shapefile for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The Northern Territory coastline shapefile was derived from a compilation of multiple datasets.

National mineral potential for sediment-hosted zinc-lead mineral systems in Australia Version 1.0

Australian sediment-hosted mineral systems are important sources of base metals and critical minerals that are vital to delivering Australia’s low-carbon economy. In Australia, sediment-hosted resources account for ~82% and ~86% of the total zinc (Zn) and lead (Pb) resources respectively. Given their significance to the Australian economy, four national-scale mineral potential models for sediment-hosted Zn-Pb mineral systems have been developed: clastic-dominated siliciclastic carbonate, clastic-dominated siliciclastic mafic, Mississippi Valley-type and Irish-type. In addition to the potential for Zn-Pb mineralisation, the uncertainty related to data availability has been examined. The mineral potential models were created using a mineral systems-based approach where mappable criteria have been used to assess the prospectivity of each system. Each model has been derived from a large volume of precompetitive geoscience data. The clastic-dominated siliciclastic carbonate mineral potential model predicts 92% of known deposits and occurrences within 15.5% of the area, the clastic-dominated siliciclastic mafic mineral potential model predicts 85% of deposits and occurrences within 27% of the area, and the Mississippi Valley-type mineral potential model predicts 66% of known deposits and occurrences within 31% of the area. Each model successfully predict the location of major sediment-hosted Zn-Pb deposits while highlighting new areas of elevated prospectivity in under-explored regions of Australia, reducing the exploration search space by up to 85% for sediment-hosted Zn-Pb mineral systems.

Hydrogeological architecture of the Great Artesian Basin: a consistent tool for future groundwater management

The Great Artesian Basin (GAB) is the largest groundwater basin in Australia. It underlies nearly one quarter of the continent, including parts of Queensland, New South Wales, South Australia and the Northern Territory. Groundwater from the GAB is a vital resource for agricultural and extractive industries, as well as for community water supply. It supports cultural values and sustains a range of groundwater-dependent ecosystems. 
Water managers from each jurisdiction manage their GAB resources using hydrogeological conceptualisations based on diverse historic nomenclature. However, GAB resources are continuous across borders and recent studies have shown high spatial variability in the hydrostratigraphic units across the basin. Therefore, there is a clear need to map the geological complexity consistently at a basin-wide scale in order to provide a hydrogeological framework to underpin effective long-term management of GAB water resources.
The present study compiles and standardises existing and newly interpreted biostratigraphic and well formation picks from geological logs, 2D seismic and airborne electromagnetic data in a consistent chronostratigraphic framework. This framework was used to correlate geological units across the basin.
Correlating the chronostratigraphy across the basin revealed age equivalent sediments deposited in different depositional environments during transgressive and regressive alternation events. Rigorous biostratigraphic control, using a common unified zonation scheme was used to identify lithological correlations. Rock properties were attributed based on sediment facies deposited during similar geological events.
The approach provides a consistent way of mapping the distribution and properties of aquifers and aquitards across the whole GAB. The refined correlation of Jurassic and Cretaceous units between the Surat and Eromanga basins improves the resolution of our understanding of hydrogeological unit geometry and lithological variation that may influence groundwater flow within and between aquifers.
The 3D hydrogeological architecture provides a model to refine hydrogeological conceptualisations and assist in improving basin water balance estimates.
