Parkes 1 100k total count 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 Parkes 1 100k total count grid geodetic has a cell size of 0.00042 degrees (approximately 43m) and shows the terrestrial dose rate of the Forbes Detail, NSW, 1993. The data used to produce this grid was acquired in 1993 by the NSW Government, and consisted of 49055 line-kilometres of data at a line spacing between 200m and 400m, and 100m terrain clearance.

Delny-Mount Sainthill Fault System, eastern Arunta Block, Central Australia

The Delny-Mount Sainthill Fault System, a distinctive feature on satellite photographs, can be traced as a well-developed geological and geophysical feature extending some 130 km across the Arunta Block, central Australia. It has a slightly north-of-west trend, from 4 km south of Mount Thring (22Â°49S, 136Â°02E) to 5 km south of Delny Outstation (22Â°33S, 134Â°49S) (Figs 1, 2). The deformed nature of the rocks at Mount Saint4iIl was first noted by Smith and others (1960), who described a blastomylonite derived from nearby granite, and recorded the gradational contact between deformed and undeformed units. Shaw and Warren (1975) mapped the Delny section of the Fault System. The nature of the remainder of the Fault System and its continuity was recognised during rapid reconnaissance to provide data for interpretation of new coloured aerial photography in the 1976 field season.

Igneous and metamorphic rocks of Cape York Peninsula and Torres Strait

A broad ridge of Precambrian and Palaeozoic igneous and metamorphic rocks extends for 450 km along the east side of Cape York Peninsula, from the Mitchell River in the south to Temple Bay. From Cape York a submerged ridge of Palaeozoic igneous rocks extends across Torres Strait to Papua. The metamorphic rocks crop out in four separate areas, but are all probably part of the same Precambrian sedimentary sequence. They have been subjected to high-temperature/lowpressure regional metamorphism, and the metamorphic grade increases eastwards from phyllite of the greenschist facies to gneiss of the amphibole facies. They consist mainly of mica schist and quartzite, with local occurrences of greenstone, calc-silicate rocks, marble, and iron-rich rocks, and are intruded by dolerite in the south. The Cape York Peninsula Batholith is composed of adamellite and subordinate granodiorite and granite. It is intrusive into the discontinuous belt of metamorphic rocks over a distance of at least 400 km. The age of the batholith is uncertain, but preliminary isotopic analyses indicate that it is probably middle Palaeozoic. In the Lower Carboniferous coal-bearing sediments were laid down in small basins. The thick sheets of acid welded tuff and subordinate lavas in Torres Strait, which are intruded by large bodies of granite and porphyritic microgranite, are probably Carboniferous, and the acid pyroclastics and associated high-level granites south of Temple Bay are Carboniferous or Permian. In the Mesozoic, coarse sandstone and conglomerate followed by finer sediments were laid down in the trough between the two basement ridges. Tertiary uplift on faults along the east side of the peninsula resulted in the deposition of poorly consolidated sandstone and conglomerate. A plug of olivine nephelinite was emplaced near the faults, and in the Pleistocene olivine basalt lava and pyroclastics were erupted from small volcanoes in the northeastern part of Torres Strait. Most of the main structures in the peninsula, such as the fold axes and foliation in the metamorphics, the faults, and the long axis of the batholith, have a northerly trend. The Palmerville Fault is a major structure which has been active from Silurian time onwards. Alluvial and reef gold were mined extensively in Cape York Peninsula and in Torres Strait late in the 19th century, and small quantities of wolfram and alluvial tin have also been won. The deposits of iron and manganese near Iron Range and the silica sand on the Mesozoic sediments north of Temple Bay have not yet been exploited. Traces of antimony, arsenic, copper, lead, zinc, and molybdenum have been reported, and occurrences of bauxite, coal, mica, heavy-mineral beach sand, and limestone are known.

Cobar P5009 EXT 2 reduced to pole fft 1st vertical derivative grid

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 Cobar P5009 EXT 2 reduced to pole fft 1st vertical derivative grid is the first vertical derivative of the TMI RTP grid of the Cobar Magnetic and Radiometric Survey, 2021 survey.
This grid has a cell size of 0.00039074 degrees (approximately 40m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2021 by the NSW Government, and consisted of 53617 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 Cobar Magnetic and Radiometric Survey, 2021 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.
