A sabkha model for the deposition of part of the Proterozoic McArthur Group of the Northern Territory, and its implications for mineralisation

Abundant pseudomorphs and relicts of gypsum, anhydrite, and halite occur in the Mallapunyah Formation and Amelia Dolomite of the Proterozoic McArthur Group of the Northern Territory. The rocks have undergone a complex history, in which several stages can be detected. These are: (a) They were deposited in a regressive/transgressive cycle with frequent minor oscillations. The sedimentary sequence shows a striking resemblance to the Pleistocene and Holocene sediments of the Abu Dhabi sabkha. (b) The evaporites were emplaced diagenetically after formation of black chert and early dolomite. Deposits in the McArthur Group sections can be closely compared with the early diagenetic facies zones of Abu Dhabi. By analogy with the Holocene the positions of particular evaporite parageneses can be located within the palaeo-sabkha. (c) Textures indicating dehydration of gypsum to anhydrite and vice versa can be detected, but the sulphate evaporites, and some of the halite, have been replaced by ferroan carbonate during burial diagenesis, at a depth of burial estimated at over 1 km. Sulphate-rich brines which also contained high metal concentrations were released at this time, and made their way through a number of accessways to overlying formations. These brines provided, at least in part, a source of sulphate and of metals for mineralisation in the Emmerugga Dolomite and Barney Creek Formation. (d) Later vadose and phreatic activity resulted in minor copper mineralisation, and in cementation and recrystallisation of the carbonates. Silcrete and magnesite-rich crusts are common on beds of replaced evaporite minerals. (e) The presence of an arid Abu Dhabi-like sabkha indicated the prevalence of a particular climatic regime. If these same climatic conditions can be identified in northwest Queensland, there exists the possibility for climatic stratigraphic correlation at an intermediate level between radiometric, and micropalaeontological and magneto-stratigraphic correlation.

Seabed Mud Content Across the Australian Continental EEZ, 2011

This dataset provides the spatially continuous data of seabed mud content (sediment fraction &lt; 63 Âµm) expressed as a weight percentage ranging from 0 to 100%, presented in 0.01 decimal degree resolution raster format. 
The dataset covers the Australian continental EEZ, including seabed surrounding Tasmania. It does not include areas surrounding Macquarie Island, and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands or Australia's marine jurisdiction off of the Territory of Heard and McDonald Islands and the Australian Antarctic Territory.
This dataset supersedes previous predictions of sediment mud content for the Australian Margin with demonstrated improvements in accuracy. Accuracy of predictions varies based on density of underlying data and level of seabed complexity. Artefacts occur in this dataset as a result of insufficient samples in relevant regions. This dataset is intended for use at national and regional scales. The dataset may not be appropriate for use at local scales in areas where sample density is insufficient to detect local variation in sediment properties. To obtain the most accurate interpretation of sediment distribution in these areas, it is recommended that additional samples be collected and interpolations updated.

2018 National Tropical Cyclone Hazard Assessment

The 2018 Tropical Cyclone Hazard Assessment (TCHA18) provides an evaluation of the likelihood and intensity (“how big and how often”) of the occurrence of tropical cyclone winds across the Australian region, covering mainland Australia, islands and adjacent waters. It is a probabilistic evaluation of the expected maximum gust wind speeds with a range of annual exceedance probabilities (or conversely, average recurrence intervals). The assessment is derived using a statistical-parametric model developed by Geoscience Australia called the Tropical Cyclone Risk Model (TCRM). Maximum 0.2-second duration, 10-metre above ground wind speeds are calculated for Standard Australia's AS/NZS 1170.2 (2011) terrain category 2 (0.02 m roughness length) surface conditions, over a 0.02 degree grid across Australia. Maps of average recurrence interval (ARI) wind speeds of 100- and 500-year ARI are provided in a separate product suite.

South Nicholson Basin seismic interpretation

The South Nicholson Basin and immediate surrounding region are situated between the Paleo- to Mesoproterozoic Mount Isa Province and McArthur Basin. Both the Mount Isa Province and the McArthur Basin are well studied; both regions host major base metal mineral deposits, and contain units prospective for hydrocarbons. In contrast, the South Nicholson Basin contains rocks that are mostly undercover, for which the basin evolution and resource potential are not well understood. To address this knowledge gap, the L210 South Nicholson Seismic Survey was acquired in 2017 in the region between the southern McArthur Basin and the western Mount Isa Province, crossing the South Nicholson Basin and Murphy Province. The primary aim of the survey was to investigate areas with low measured gravity responses (‘gravity lows’) in the region to determine whether they represent thick basin sequences, as is the case for the nearby Beetaloo Sub-basin. Key outcomes of the seismic acquisition and interpretation include (1) expanded extent of the South Nicholson Basin; (2) identification of the Carrara Sub-basin, a new basin element that coincides with a gravity low; (3) linkage between prospective stratigraphy of the Isa Superbasin (Lawn Hill Formation and Riversleigh Siltstone) and the Carrara Sub-basin; and (4) extension of the interpreted extent of the Mount Isa Province into the Northern Territory.

AUSGeoid98 v.1.0 data files: Seemore (sh51-12)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

The geology and mineral resources of the Hatches Creek Wolfram Field, Northern Territory

Wolframite is the commonest source of tungsten, but scheelite is present in some mines. Minerals of bismuth, copper, molybdenum, lead, tin, and iron have been identified in association with the tungsten minerals. Minor amounts of gold are also present. The Hatches Creek Wolfram Field is situated near the north-eastern end of the Davenport Range in the Northern Territory. The Stuart Highway, a bitumenized road linking the port of Darwin with Tennant Creek and Alice Springs, crosses the Range at the north-western end. Wolfram deposits are present at Wauchope, The Devil's Marbles, Moscluito Creek, Kurunelli, Epenarra, Elkedra, and Hatches Creek; only the Wauchope and Hatches Creek deposits have proved to be economically important. The Wauchope deposits have been investigated by Sullivan (1952). The Hatches Creek Wolfram Field is defined for the purpose of this report as a roughly triangular area bounded by Hatches Creek, Mia Mia Creek, and the Hit or Miss Gully (Pl. 2). The area extends roughly seven miles in a northerly direction and is about three miles across at the base. Only two small tungsten bearing reefs and some reefs reputed to carry gold lie outside this area.
