TEISA - Area A8, SA, 1999 (P2008), 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 TEISA - Area A8, SA, 1999 survey were acquired in 1999 by the SA Government, and consisted of 1350 line-kilometres of data at 400m line spacing and 80m 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.

Southern Yilgarn (Bremer Bay), WA, 2004 (P1067), elevation line data

The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation 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 Southern Yilgarn (Newdegate, Ravensthorpe, Bremer Bay), WA, 2004 survey were acquired in 2004 by the WA Government, and consisted of 99719 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Fossil shark teeth dredged from the Great Australian Bight

Two fossil shark teeth found in rocks dredged from the walls of submarine canyons in the Great Australian Bight are described.  One of them, found in chalk ooze of Late Oligocene age, is referred to Isurus sp. cf. I. desori. The other, from a Late Cretaceous glauconitic sandstone, is described as a new species of Echinorhinus - the first time a fossil of this family has been identified in Australia.  Reference is made to a misidentified tooth from the Albian of Queensland, viz. Corax australis Chapman 1909, which may be congeneric with the new Echinorhinus species.

Australian resources of sulphur-bearing minerals

Sulphur is a non-metallic element which occurs in the free form as native sulphur and in combination with metals as sulphides and sulphates. The principal sulphide minerals used, or usable, for their sulphur content are those of iron (pyrite, pyrrhotite and marcasite), copper and iron (chalcopyrite), lead (galena) and zinc (sphalerite and the iron-bearing varieties known as marmatite). The principal sulphate minerals are those of calcium (anhydrite and gypsum) and of potassium and aluminium (alunite). Sulphuric acid is made in large quantities from sulphide minerals; either by roasting pyrite concentrates specifically for that purpose, by roasting or smelting base-metal ores and concentrates, or, in smaller quantities, from sulphate minerals as a co-product of cement manufacture. Sulphur is used principally for making sulphuric acid (94% in 1949), which is one of the most important substances in modern chemical industry. Sulphuric acid is made in Australia and consumed almost entirely in the manufacture of chemical fertilizers (mainly superphosphate) for the agricultural and pastoral industries. In more industrialized countries, a considerable amount of sulphuric acid is used in heavy industries. Sulphur-bearing materials used to make sulphuric acid include- Brimstone-native sulphur (100% sulphur); pyrite or pyrite concentrates iron sulphide (50% sulphur); zinc concentrate zinc sulphide (32% sulphur); anhydrite calcium sulphate (23.6% sulphur). Australia has no deposits of native sulphur. It imports brimstone and also uses domestic pyrite concentrates and zinc concentrates. Fortunately, Australia has several large deposits of sulphide materials. The largest are at Mount Isa and Mount Morgan, in Queensland, Broken Hill and Captain's Flat in New South Wales, Mount Lye11 and Read-Rosebery in Tasmania, Nairne in South Australia, and Norseman in Western Australia.

Kingoonya - TMI RTP 1VD grid (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. .
 This Kingoonya - TMI RTP 1VD grid (AWAGS) is the first vertical derivative of the TMI RTP grid of the Kingoonya Airborne Magnetic Radiometric and DEM survey, SA, 2018 survey.
This grid has a cell size of 0.0004 degrees (approximately 41m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2018 by the SA Government, and consisted of 149477 line-kilometres of data at 200m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the Kingoonya Airborne Magnetic Radiometric and DEM survey, SA, 2018 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.
