Distribution of sulphides and PGE within the porphyritic websterite zone of the Munni Munni Complex, Western Australia

The Munni Munni Complex is a boat-shaped layered intrusion, divided into a lower ultramafic 'keel', up to 1850 m thick, overlain by a gabbroic sequence at least 3000 m thick. The top of the ultramafic series is marked by a 20-80 m thick porphyritic websterite zone (PWZ), that extends laterally to form a 200 m thick layer of pyroxenite along the walls of the intrusion. Platinum-group element (PGE)-enriched disseminated sulphides occur within the top 20 m of the PWZ unit along its entire exposed strike length, with maximum total PGE grades up to 8 ppm over 500 mm widths. The PWZ marks a pronounced discontinuity in mineral composition trends within the intrusion, between uniform relatively high Mg# and Cr-rich pyroxenes in the main part of the ultramafic series, to gabbroic cumulates showing a monotonous trend of declining Mg# due to closed system fractionation in a large chamber. The Cr2O3 content of cumulus augite shows a dramatic drop from about 0.2% to less than 0.05% over less than 4 m near the top of the PWZ.
Disseminated cumulus sulphides are abundant within an interval from 5 m above the gabbro contact to 15 m below it. Two sulphide components are present. The first is a relatively PGE-poor component, characterized by coincidence of peak Cu, Ni, S and PGE abundances. The second is a variable composition component, strongly PGE enriched at the base and depleted at the top, characterized by systematic offsets between the peak PGE and Cu abundances. The 'offset' sulphides always occur above the 'coincident' sulphides, and their first appearance corresponds to the sudden drop in Cr2O3 content of clinopyroxene within the PWZ.
The coincident sulphides are interpreted to have formed by batch equilibration of sulphide liquid droplets during the magma mixing event that produced the PWZ. The offset sulphides formed subsequently by fractional segregation and gravity settling of sulphide liquid droplets from a stagnant hybrid melt layer dominated by the gabbroic component. The observed lateral distribution of PGE-rich sulphides in the PWZ is inconsistent with derivation of PGE from trapped liquid in underlying cumulates and provides strong evidence for the existence of primary PGE-enriched cumulus sulphide liquid.

Angas Bremer Hills elevation grid geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Angas Bremer Hills elevation grid geodetic is elevation data for the SMMSP - MagSpec - Angas Bremer Hills, SA, 2002. (2002/01). This survey was acquired under the project No. 910 for the geological survey of SA. The grid has a cell size of 0.00021 degrees (approximately 21m).  This grid contains the ground elevation relative to the geoid for the SMMSP - MagSpec - Angas Bremer Hills, SA, 2002. (2002/01). It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

Orbost, Vic, 1994 VIMP Survey (GSV2665) (P654), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected 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.
 This Orbost, Vic, 1994 VIMP Survey (GSV2665) (P654), radiometric line data, AWAGS levelled were acquired in 1994 by the VIC Government, and consisted of 20638 line-kilometres of data at 200m line spacing and 90m 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.

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 Pilbara Block (Roy Hill, Newman), WA, 1985 survey were acquired in 1985 by the WA Government, and consisted of 29956 line-kilometres of data at 1500m line spacing and 150m 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.

Notes on the Calvert Hills 4-mile geological sheet

A basement of Precambrian volcanic and granitic rocks is overlain by two sequences of shallow-water sedimentary rocks regarded as of Upper Proterozoic age, and by a sequence of terrestrial and paludal or lacustrine sedimentary rocks of Upper Jurassic to Lower Cretaceous age. The older Upper Proterozoic sequence contains volcanics and intrusives and has been moderately folded. The younger Upper Proterozoic sequence has been weakly folded.
Remnants of Miocene (?) laterite occur near the headwaters and on the interfluves of streams flowing towards the Gulf of Carpentaria.
Faults (both normal and transcurrent) and joints with a dominant north-west trend are numerous. The most prominent fault, the Calvert Hills fault is transcurrent, quartz-filled in places, and trends north-west across the sheet.
The Precambrian basement rocks contain small deposits of uranium, copper, tin and gold. The older sequence of Upper Proterozoic rocks contains small deposits of uranium and copper. The younger sequence contains small deposits of copper and manganese. Some of the sedimentary rocks are aquifers and would supply adequate quantities of bore water for stock.
Two second order relief forms occur; one the dissected country drained by streams flowing to the Gulf of Carpentaria, the other the tableland country drained by streams flowing into an internal drainage basin. Fossil erosion surfaces are present in the area. Some land-forms are controlled by structure.

AUSGeoid98 v.1.0 data files: Charleville (sg55-10)

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.

Mafic dyke swarms of the western Musgrave Block, central Australia: their geochemistry, origin, and relationships to the Giles Complex

Several petrographically and geochemically distinct suites of mafic dykes crop out in the Mesoproterozoic Musgrave Block.  Intergranular dolerites (group A), as well as the voluminous Giles Complex layered mafic-ultramafic intrusions and Tollu Group basaltic volcanics, were formed by large-scale melting of heterogeneous enriched subcontinental lithospheric mantle about 1080 Ma ago, more than 100 m.y. after the 1200-Ma regional high-grade metamorphism of the Musgrave Block country rocks. The coeval Kulgera (eastern Musgrave Block) and Stuart (Arunta Block) dyke swarms are chemically and isotopically similar.  Slightly younger (-1000 Ma), particularly heterogeneous olivine dolerites (group C) were also derived from a similarly enriched source. Mantle heterogeneity was apparently both lateral (as group C dolerites show significant geographical variations) and vertical (because chemically distinct dyke suites of similar age crop out in the same area).  Microgabbro dykes and sills associated with troctolitic intrusions of the Giles Complex are compositionally similar to both gabbronorite intrusions of the Giles Complex and to group A dolerite dykes therein.  The least fractionated microgabbros are probably representative of an evolved magma that was parental to the major gabbroic intrusions of the Giles Complex, and underwent some degree of high-pressure pyroxene Â± olivine fractionation. They cannot be directly parental to the leucotroctolite cumulates. which reflect much more extensive high-pressure fractionation before they were emplaced.  Quartz dolerites emplaced 800 Ma ago (group B) were derived by higher-pressure partial melting of a much less enriched (-Nd +2.8 to +3.8), homogeneous asthenospheric mantle source, probably related to mantle-plume activity. They are virtually identical chemically and isotopically with dykes, including the Amata (eastern Musgrave Block) and Gairdner (Gawler Craton) dyke swarms, that crop out over a distance of more than 1000 km.
