Preliminary assessment of the Ni-Cu-PGE potential of the Harris Greenstone Belt, Gawler Craton

The Harris Greenstone Belt in the central Gawler Craton of South Australia has potential for Archaean Ni-Cu-PGE sulphide and Archaean-Proterozoic lode-Au mineralising systems. This map is a preliminary interpretation of the Precambrian basement geology based on aeromagnetics, gravity, and diamond drilling. It highlights the extensive distribution of poorly exposed Archaean komatiites and associated rocks (green) that have a strike extent of at least 300 km. The regional pattern of linear komatiitic sequences associated with ovoid granitic plutons and province-wide shear systems, is very similar to the economically important Eastern Goldfields Province in the Yilgarn Craton, Western Australia.
The ca. 2520 Ga Lake Harris Komatiite in the central Gawler Craton of South Australia is the first documented komatiite outside the West Australian Craton and the easternmost occurrence of such primitive ultramafic rocks in Australia. The steeply dipping ultramafic sequence consists of komatiite cumulates, high- to low-Mg komatiite, komatiitic and tholeiitic basalt, and pyroxenite cumulates. The komatiitic rocks display a range of quenched and cumulus textures defined by the different habits of olivine and its alteration products. Trace sulphides form very small (0.01-0.2 mm) single-phase disseminated grains and coarser disaggregated grains. 
Thick ponded lava lake and distal composite sheet flow facies have been identified in the magmatic environment. Systematic whole rock and mineral chemical trends indicate that despite the effects of recrystallisation and re-equilibration during amphibolite-facies metamorphism, the original magmatic geochemical profiles are largely preserved. The whole-rock data for the Lake Harris Komatiite does not show any obvious Ni depletion during fractionation but indicate a strong olivine control in dominantly S-undersaturated environments. The Lake Harris Komatiite has chemical and initial Nd isotope characteristics similar to typical Al-depleted Archean komatiites.

Tanami East, NT, 1987 (P530), 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 Tanami East, NT, 1987 (P530), radiometric line data, AWAGS levelled were acquired in 1987 by the NT Government, and consisted of 14260 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. This survey data is essentially levelled to AWAGS.

The phosphate deposits of Bellona Island

Bellona Island, British Solomon Islands, was visited by a survey team of the Bureau of Mineral Resources, as part of the search for phosphate deposits. The island is a raised coral atoll and has a phosphate deposit mostly of phosphatic clay, overlying and infilling between limestone pinnacles and in chimneys on the old lagoon floor. It is estimated that 4,500,000 tons of the clay with an average grade of 22.2% P205 and 700,000 tons of phosphatic sand averaging 30.3% P205 are recoverable. The bulk of material is rich in iron and alumina and its value as an economic deposit is doubtful.

Temporal clustering of surface ruptures on stable continental region faults: a case study from the Cadell Fault scarp, southeastern Australia

A characteristic of Australian stable continental region (SCR) faults appears to be the temporal clustering of surface rupturing earthquakes.  With the possible exception of active faults in the Flinders Ranges and Mt Lofty Ranges regions of South Australia, active periods of earthquake activity comprising a finite number of events are separated by much longer periods of seismic quiescence.  This behaviour poses particular problems for seismic hazard assessment in that it implies that recurrence of large earthquake events is not random (Poisson) as is implicitly assumed in most seismic hazard assessment methods.  We present a model that helps to conceptualise the points critical to understanding the hazard posed by intraplate faults and in modelling this hazard probabilistically. Specifically, we look to identify whether the SCR fault in question is about to enter an active period, is in the midst of an active period, or is in a quiescent period.  In relation to this issue it becomes important to know how many previous ruptures the fault has generated in its current active period (should it be in one), and specifically, if a fault is in an active period, what is the average recurrence interval and what is the variability around this average.  This average could be incorporated statistically into probabilistic seismic hazard assessments.

Thangoo No. 1 And No. 1a Wells, Western Australia Of West Australian Petroleum Pty Limited

Thangoo No. lA well was drilled as a result of mechanical difficulties encountered at the drilled depth of 3 ,475 feet in Thangoo No. 1 well which were insurmountable and prevented further operations on this well. Total loss of circulation at 3,475 feet in Thangoo No. 1 well resulted in unexpected total collapse of the hole below the 10 3/4" casing in a section of friable sandstone and conglomerate (Grant Formation). In Thangoo No. lA well these formations were cased off. A lost circulation zone was tested for potential hydrocarbon production and found to contain water only. The well was drilled to 5,429 feet into basement rocks (programmed depth 4,500 feet).
Excellent hole control was maintained to total depth by drilling below the 16" conductor shoe with high pH, low shear and waterloss, freshwater mud.
The 1,366 feet of Mesozoic and 1,377 feet of Permian section in Thangoo No. lA closely resemble that of Thangoo No. 1. The Ordovician section is 2,318 feet thick, consisting of 695 feet of Goldwyer Formation (new name) and 1,623 feet of Thangoo Limestone (amended name). Basement, consisting of Precambrian phyllite , was encountered at 5,100 feet in Thangoo No. lA.
Traces of oil were observed throughout the Ordovician section. Oil shows are confined predominantly to vuggy veins of coarse crystalline dolomite. A minor show was also observed in the sandstone of the basal unit of the Thangoo Limestone. A porous zone within the Thangoo Limestone, causing some lost circulation, appeared at about 3,670 feet in Thangoo No. lA. A formation test of this zone recovered only brackish water (11,999 ppm. total salts) with no signs of oil or gas. It is possible that the small shows of oil in the Thangoo Limestone are retained by the impervious Goldwyer Formation, as no shows were present in the Roebuck Bay and Dampier Downs wells, where porous Permian rocks directly overlie the Thangoo Limestone.
The correlation of the sections of the Thangoo Limestone in all the exploratory wells on the Broome Platform indicates that the Thangoo No. lA well occupies a low structural position. Consequently the objectives of testing the structure in the Ordovician and Permian Grant Formation were not achieved.
The chances of finding commercial oil accumulations in the Ordovician section of the South Canning Basin in the vicinity of Thangoo Nos. 1 and lA are very small at this time, because of the low source rock potential and flushing by meteoric waters of the Thangoo Limestone,  the lack of porosity in the Goldwyer Formation, and the difficulties experienced in resolVing the structure of the Ordovician with present seismic methods.

Great Artesian Basin - Cadna-owie Hooray Aquifer - Fluoride Concentration

Data used to produce the predicted Fluoride map for the Cadna-owie - Hooray Aquifer in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al., 2015).
There are four layers in the Cadna-owie - Hooray Aquifer  Fluoride map data
A. Location of hydrochemistry samples (Point data, Shapefile)
B. Predicted Concentration (Filled contours , Shapefile)
C. Predicted Concentration Contours (Contours, Shapefile)
D. Prediction Standard Error (Filled contours , Shapefile)
The predicted values provide a regional based estimate and may be associated with considerable error. It is recommended that the predicted values are read together with the predicted error map, which provides an estimate of the absolute standard error associated with the predicted values at any point within the map.
The predicted standard error map provides an absolute standard error associated with the predicted values at any point within the map. Please note this is not a relative error map and the concentration of a parameter needs to be considered when interpreting the map. Predicted standard error values are low where the concentration is low and there is a high density of samples. Predicted standard errors values can be high where the concentration is high and there is moderate variability between nearby samples or where there is a paucity of data.
Concentrations are Fluoride in mg/L.
Coordinate system is Lambert conformal conic GDA 1994, with central meridian 134 degrees longitude, standard parallels at -18 and -36 degrees latitude.
The Cadna-owie - Hooray Aquifer Fluoride map is one of 14 hydrochemistry maps for the Cadna-owie - Hooray Aquifer and 24 hydrochemistry maps in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al, 2014).
