GSSA Warrina Dose Grid Geodetic

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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSSA Warrina Dose Grid Geodetic has a cell size of 0.00083 degrees (approximately 87m) and shows the terrestrial dose rate of the Marree-Warrina Airborne Magnetic &amp; Radiometric Survey, SA, 2012. The data used to produce this grid was acquired in 2012 by the SA Government, and consisted of 132484 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Summary Of Data And Results Otway Basin, Victoria Flaxmans No. 1 Well Of Frome Broken Hill Company Proprietary Limited

Flaxmans No. 1 Well was located within the south-eastern part of the Otway Basin, approximately 20 miles south-east of Warrnambool, on the Victorian coast. The well was drilled by Oil Drilling and Exploration Limited for Frome-Broken Hill Company Proprietary Limited, to a total depth of 11,528 feet. Drilling commenced on 3rd May, 1961 and was completed on 25th August, 1961. A full programme of logging, testing, and coring was undertaken.
The well penetrated Miocene-Oligocene sediments to a depth of 2008 feet, Eocene-Upper Cretaceous to 4833 feet, Upper Cretaceous to 6490 feet, Middle Cretaceous to 6876 feet, Lower Cretaceous to 7330 feet, and Lower Cretaceous - (?) Jurassic otway Group sediments to total depth of 11,528 feet.
Flaxmans No. 1 was drilled to test the hydrocarbon potential of the Tertiary and Mesozoic sediments in a closed seismic structure. Sixteen drillstem tests and ten production tests were undertaken but the maximum yield of 250 Mcf/D of gas from the interval 10,842 to 11,528 feet could not be maintained and the well was plugged and abandoned. Other possible reservoirs tested in the well yielded only small amounts of petroliferous gas, probably from solution in formation water.
The stratigraphic drilling operation at Flaxmans No. 1 was subsidized under the Petroleum Search Subsidy Act 1959, from 4833 feet to total depth.

Archaean Crustal Structure from Seismic Reflection Profiling, Eastern Goldfields, Western Australia : Results from the Kalgoorlie Seismic Transect

Crustal seismic reflection profiling has successfully imaged the depth extent and the internalstructure of the Archaean greenstone of the Kalgoorlie Terrane and adjacent belts. The basalcontact of the green stones is subhorizontal and gently undulating, reaching a maximum depthof 7 km. Strongly reflective, subhorizontal layering occurs below the basal contact interpretedto be gneissic basement. The basal contact is offset in several places by moderate- to shallow-dipping, strongly reflective zones which project to the surface at the position of previouslymapped shear zones. These shear zones show clear normal displacement of greenstonestratigraphy and the basal greenstone-gneiss; some sole out into the basal greenstone contactand others extend considerably deeper into the gneissic basement. Stratigraphy and major foldstructures are well delineated, and granite plutons have been constrained to tapering surf-board shapes, rather than the sheet-like forms, or diapirs. Stratigraphic units appear totruncate abruptly at the basal greenstone contact in many places suggesting significantdecollement has occurred at the contact during low-angle thrusting.
In association with the seismic traverse, a gravity traverse (200m station spacing) and airbornemagnetic traverse were carried out. The geological interpretation of seismic units is usefullyconstrained by the gravity data, which also provide evidence of changes in crustal structurealong the line.
Geochemical analysis was carried out on material collected from the bottom of each shot hole(883 samples). A suite of 30 trace elements were analysed, and these data demonstratesignificant differences in granite chemistry along the line. A number of anomalous values for avariety of elements have been identified.

Pilbara Block (Port Hedland, Marble Bar, Nullagine), WA. 1985 (P508), 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 Pilbara Block (Port Hedland, Marble Bar, Nullagine), WA. 1985 survey were acquired in 1985 by the WA Government, and consisted of 42713 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.

Brown's deposit, Rum Jungle, Northern Territory

Brown's Deposit is the westernmost known area of mineralization in the Rum Jungle area. It is situated approximately two miles northeast of Rum Jungle Railway Siding and one mile southwest of White's Deposit in an area known as Brown's Workings, which was worked for copper in the early part of the century. In June 1950, preliminary geophysical investigations revealed that a radiometric anomaly was present at the eastern end of the old copper workings, and in October 1940, a self-potential survey (Allen 1950) indicated the presence of two distinct bodies of sulphide mineralization. During 1950 a geological map of the area on a scale of 100 feet to an inch was prepared, and in 1951 mapping of the area on a scale of 40 feet and 20 feet to an inch was commenced. This work at present remains unfinished due to other commitments. Three diamond drill holes, part of an extensive programme of diamond drilling planned for the area were drilled towards the end of 1951.

Geology and mineral deposits of the Cullen mineral field, Northern Territory.

The Cullen Mineral Field, lying in the southern central part of the Pine Creek Geosyncline, contains early Proterozoic metasediments of the Namoona, Mount Partridge, South Alligator, and Finniss River Groups. The metasediments, originally shale, siltstone, quartz sandstone, conglomerate, greywacke, dolomite, dolarenite, dololutite and tuff, were intruded by pre-orogenic sills of Zamu Dolerite before being deformed and metamorphosed to greenschist facies between 1870 and 1780 Ma. These rocks, together with unconformably overlying felsic volcanics (El Sherana and Edith River Groups), were extensively metamorphosed by syn- to post-orogenic granitoids of the Cullen Batholith emplaced between 1830 and 1780 Ma. The Batholith contains granodiorite, several varieties of granite and leucogranite, bodies of monzonite, and younger syenite dykes. Largely undeformed Middle Proterozoic, Palaeozoic, and Mesowic strata rest on earlyProterozoic rocks with marked regional unconformity and form tablelands and plains bordering the mineral field to the southwest and southeast. The main forms of metal occurrence are: hydrothermal veins and stockworks (Sn, W, Au, Ag, Pb, Zn, Cd, Cu, Bi, As, D, and Mo); volcanogenic stratabound massive sulphide deposits (Au, Ag, Cu, Pb, and Zn); alluvial deposits (Au and Sn); and residual massive oxide deposits (Fe and Mn).The vast majority of mines have worked hydrothermal deposits which are mostly located in north to northwest-trending faults, shear zones, and associated structures within early Proterozoic metasediments and granitoids. Pyritic, dolomitic and carbonaceous strata are preferentially mineralised, especially within the Koolpin and Mount Bonnie Formations. The distribution of deposits within the contact aureole defines a zonation of uranium closest to granite, through tungsten, copper, tin, silver-lead, to gold with increasing distance from the granitoid contact. This nation probably reflects decreasing temperatures within the contact aureole at the time of generation of a variety of metal-bearing fluids, either during granitoid emplacement or later. A magmatic source for some of the metals is indicated, particularly in late-stage, highly fractionated leucogranites which form cusps peripheral to the main body of the Cullen Batholith. The Cullen Mineral Field has been a major centre of metal production, mainly for gold, silver, lead, copper, tin, tungsten and iron. Minor zinc, cadmium. bismuth, arsenic, molybdenum, uranium and limestone have also been won.
