Geology and mineral deposits of The Granites-Tanami and Tennant Creek Inliers, Northern Territory

The Palaeoproterozoic Tennant Creek Inlier (TCI) and The Granites-Tanami Inlier (GTI) share similarities in their stratigraphy and tectonic evolution. Both are characterised by a sequence of flysch sediments and volcanics that accumulated in an intracratonic transtensional basin which was deformed (D1), metamorphosed and intruded by syn-orogenic I-type granitoids during the Barramundi Orogeny.  Fluvial to shallow marine sediments, accompanied by felsic volcanism (plus mafics in the Davenport province) and penecontemporaneous subvolcanic intrusive activity, were deposited unconformably over the early rift sequence.  Two episodes of mild deformation (D2 and D3) folded and faulted the sequence to produce basin and dome structures which were subsequently intruded by biotite-muscovite granites.  Gold is the most important mineral commodity mined within both the inliers.  It is concentrated in deposits which have a regional stratigraphic control (Mount Charles beds- GTI, Warramunga Formation ironstones- TCI) in combination with various structural controls at the local scale. The origin of the Au mineralising fluids is uncertain. Late felsic intrusives associated with the Barramundi Orogeny probably contributed magmatic fluid at the Au-Cu-Bi depositional stage at Tennant Creek, although a significant metamorphic fluid component is also evident. Vein quartz-hosted W, Au, Cu, Bi , U, Ag/Pb mineralisation in the Davenport province is within volcanics and sediments of the Ooradidgee Subgroup, and igneous intrusives (mainly gabbro/dolerite). The metal-bearing hydrothermal fluids are inferred to emanate from post-orogenic two-mica granites.

5028 Block 1 (Southwest)reduced magnetic point-located data

GENERAL
 Total Magnetic Intensity (TMI) data measures variations in the intensity of the Earth's magnetic field, which includes the fields associated with the Earth's core, diurnal variations, and the magnetism of rocks in the Earth's crust.
 TMI data is used for geological mapping, mineral exploration, and environmental studies.

REDUCED DATA
 The reduced point-located data are processed to highlight the response of the subsurface geology in the Earth’s crust. It has the following reductions applied:
 1. Compensated for manoeuvre noise and heading error.
 2. Diurnal correction.
 3. Geomagnetic Reference Field correction.
 4. Tie-line levelling.
 5. Micro-levelling.

This line dataset from the Narryer survey were acquired in 2024 by the WA Government, and consisted of 415090 line-kilometres of data at 100m line spacing and 50m terrain clearance.

Seabed imagery from IN2017_V01, Sabrina Seafloor survey, East Antarctica

Six camera tow transects were completed during survey IN2017-V01 on the RV Investigator in January to March 2017. This survey focussed on the upper slope and outer continental shelf on the Sabrina Coast seafloor in East Antarctica. Camera tows targeted seafloor depths between 480 and 1680 m. Imagery was collected using the Marine National Facilities Deep Tow Camera. This system collects oblique downward facing still images with a Canon 1DX and high definition video with a Canon C300. Four DSP&amp;L 3150 High Output SeaLite Sphere lights were used, with MicroSeaLasers providing a 10cm scale guide on the images. Several sensors are also attached to the towed body, including a SBE 37 for CTD measurements, a Kongsberg Mesotech – 1007D altimeter, a Druck PMP 5074 pressure sensor and two Sonardyne USBLs for locational accuracy of the towed body. The USBL failed for tow A008CAM02, with locations recorded as ship’s position instead and camera position based on layback calculations. Images failed to record on A004CAM01, with only 2 images saved. Due to a timing error between the images and the other sensors, there is an offset between the CTD, altimeter and pressure data and the images. This is currently being resolved by the MNF. Tows were designed to run down slope to reduce potential for colliding with the bottom. All tows were run with a ship speed over the ground of approximately 2 kt. All still images were saved in jpeg format with video footage recorded to HD1080i50 format. The video data is unclipped and includes descent and ascent in the water column. Following collection still images were colour corrected in Adobe Photoshop to remove the blue bias. 

Images are available on the NCI with the following file structure:

An extensive offshore sand bar field in the western Baltic Sea

In the breaker zone in southeastern Gelting Bay, east of Flensburg in north Germany, a field of up to 20 parallel relatively small-scale offshore sand bars has developed. The bars, ~lhich consist of fine to medium grained sand derived from till, are flat and asymmetrical and their steeper sides generally face the shore. Crests are as much as 1000 m long; Vlavelengths vary from 7 m inshore to 70 offshore, and heights correspondingly from 5 to 70 cm. The bars are fonned by waves driven by northwesterly tvinds, and are probably destroyed during severe storms and rebuilt as they wane.

Seas and Submerged Lands Act 1973 - Australian Maritime Boundaries 2020 - Geodatabase

Geoscience Australia has the primary role in the delineation of Australia's domestic and international maritime limits and boundaries. An output of this activity is the development of the Australian Maritime Boundaries (AMB) data. AMB is a GIS data product, replacing Australian Maritime Boundaries 2014a (AMB2014a), providing access to the data for Australia's maritime zones. AMB is a digital representation of Australia's limits and boundaries as established under the Seas and Submerged Lands Act 1973 and associated proclamations. The data also include a representation of the limits by which the scheduled and offshore areas of each of the States and of the Northern Territory are determined under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA). In the event of an inconsistency between AMB data and the limits under any legislation, the latter prevails. The data have been published by Geoscience Australia in consultation with other relevant Commonwealth Government agencies including the Attorney-General's Department, the Department of Foreign Affairs and Trade and the Australian Hydrographic Office. 

This version has been updated to reflect the 2018 Timor Sea Treaty.

AMB data comprise the territorial straight baselines and the outer limits of each zone, together with maritime boundaries determined by treaties between Australia and neighbouring countries. All data coordinates are supplied in the GDA94 datum. The data reflects the location of the coastline within the constraints of available source material at the time of production. AMB Data can also be viewed on-line via AMSIS (http://www.ga.gov.au/marine/jurisdiction/amsis.html). Product Specifications Coverage: Australia including all external territories Currency: August 2019. Coordinates: Geographical Datum: GDA94 (functionally equivalent to WGS84). Format: ESRI Geodatabase and REST web service - free online.
The area of coverage of the AMB data is for the whole of the Australian marine jurisdiction which includes waters adjacent to the mainland, offshore islands and External Territories.  The geographical extent is approximately between the latitude limits of 7 S to 70 S and the longitude limits 40 E to 175 E.
This dataset includes the following disclaimer:
AMB data is a digital representation of the territorial sea baseline and of the outer limits of Australia's maritime zones.  The baseline and zones are established under the Seas and Submerged Lands Act 1973.  The data also includes a representation of the limits by which the waters adjacent to each of the Australian States and of the Northern Territory are determined under the Coastal Waters (State Powers) Act 1980, Coastal Waters (Northern Territory Powers) Act 1980 and the Offshore Petroleum and Greenhouse Gas Storage Act 2006.  In the event of an inconsistency between AMB data and the baselines and limits under the legislation, the latter prevails.

Australian Petroleum Systems. Roebuck and Offshore Canning Basins - Beagle Sub-basin module

This module is part of the AGSO-APIRA Australian Petroleum Systems Project. 
Eight basin modules were examined which covered almost the entire North West Shelf, the Petrel Sub-basiTn, as well as the Papuan basin in PNG. 
Two relational databases were established containing the biostratigraphic data (STRATDAT) and reservoir, facies and hydrocarbon shows data (RESFACS). These databases were linked by application programs which allow time series searching using geologically intelligent routines. 
Petroleum systems analyses were conducted on each area, with key results focussing upon the comparison of source quality and timing of generation between similar systems in different areas.

Results of Two Dry-season Surveys of Keppel Bay and Casuarina Creek: Biogeochemical Properties of the Water Column and Underlying Sediments

The Fitzoy Estuary is one of several macrotidal estuaries in tropical northern Australia that face ecological change due to agricultural activities in their catchments. The biochemical functioning of such macrotidal estuaries is not well understood in Australia, and there is a pressing need to identify sediment, nutrient and agrochemical pathways, sinks and accumulation rates in these extremely dynamic environments. This is particularly the case in coastal northern Queensland because the impact of water quality changes in rivers resulting from vegetation clearing, changes in land-use and modern agricultural practices are the single greatest threat to the Great Barrier Reef Marine Park.

Integrated approach to CO2 storage assessment in the offshore South Perth Basin, Australia

As part of the Australian Government National CO2 Infrastructure Plan (NCIP), Geoscience Australia is undertaking CO2 storage assessment of the Vlaming Sub-basin located offshore Western Australia in the southern Perth Basin. The Vlaming Sub-basin is a Mesozoic depocentre containing up to 14 km of sediments. Close proximity of the basin to industrial polluters in the Perth area dictates the need to find CO2 storage solutions in this basin. The main reservoir unit identified as suitable for storage of CO2 is the Early Cretaceous Gage Sandstone deposited in paleo-topographic lows of the Valanginian breakup unconformity. The reservoir unit is laterally extensive (over 1,500 km2) and over most of the area reasonably thick (100 - 300 m). It lies at depths between 1400 and 2000 m below the seafloor, which is suitable for injection of the supercritical CO2 and makes it an attractive target for the long-term storage. The reservoir unit is overlain by a thick deltaic to shallow marine succession of the South Perth Shale, which represents a regional seal in the area. Carbon Storage taskforce estimated that up 1 GT of CO2 can be stored in the Gage Sandstone. The first assessment of the Vlaming Sub-basin undertaken by CO2CRC focused on evaluation of the reservoir unit and overall storage capacity. The current study is based on interpretation and integration of the seismic, well and marine datasets, both existing and acquired since the previous assessment. It includes detailed analysis of reservoir and seal properties and a comprehensive evaluation of the seal integrity risks to allow a more accurate and realistic modeling for CO2 storage.

Classification of the Australian Continental Shelf Based on Predicted Sediment Threshold Exceedance from Tidal Currents and Swell Waves

Estimates of significant wave height and period, together with tidal current speed over a semi-lunar cycle, were used to predict the area on the Australian continental shelf over which unconsolidated sediment was mobilised (threshold exceedance). These sediment-entraining processes were examined independently to quantify their relative importance on the continental shelf.

MODIS Derived Primary Productivity: Seasonal Hotspots

The dataset indicates the seasonal primary productivity hotspots of ocean surface waters. They are derived from MODIS (aqua) images using NASA's SeaDAS image processing software. The monthly chlorophyll a images between July 2002 and August 2014 are used to identify the primary productivity hotspots of the four austral seasons: winter (June, July, and August), spring (September, October and November), summer (December, January and February) and autumn (March, April and May). The extent of the dataset covers the entire Australian EEZ and surrounding waters (including the southern ocean). The value (between 0 and 1.0) of the dataset represents the likelihood of the location being a primary productivity hotspot.

This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.

Processes controlling the formation of the Mertz Drift, George Vth continental shelf, East Antarctica: evidence from 35 Khz sub-bottom profiling and sediment cores

Recently discovered drift deposits on the Antarctic continental shelf provide access to information on the Holocene palaeoceanography of the bottom current regime within deep shelf basins that were previously inaccessible. The George Vth Basin on the East Antarctic margin has been identified by oceanographers as an important source of Antarctic Bottom Water, hence the Holocene history of bottom current activity here may be relevant to variations in bottom water export.
