Devonian and Carboniferous brachiopods from north-western Australia

At least eight forms of the brachiopod genus Camarotoechia occur in the Carnarvon, Fitzroy, and Bonaparte Gulf Basins of Western Australia, four in Upper Devonian rocks and four in Carboniferous rocks. One of the Carboniferous species ranges into the Northern Territory. One species, C. lucida, is already described, three species are indeterminate, and four, C. amnica, C. puteana, C. septima, and C.eganensis, are described as new. Each species has been found only in one basin, and the genus cannot therefore be used in correlation between basins; but within each basin, species of Camarotoechia are abundant, and prove to be valuable stratigraphical indices, particularly in distinguishing Upper Devonian from Lower Carboniferous rocks.  Five brachiopod species from the Gneudna Formation of the Carnarvon Basin are described: Productella oecidua sp. nov., Camarotoeehia puteana sp. nov., Spinatrypa aspera prideri (Coleman) 1951, cf. Ladjia saltica Veevers 1959, and an indeterminate smooth spiriferid. Corals (HilI, 1954) and brachiopods (Glenister, 1956) already described from the Gneudna Formation are listed, and some corrections noted. The brachiopods described below are used in determining the age of the Gneudna Formation as Frasnian, the lower half probably middle Frasnian, the upper probably upper Frasnian.

Laverton, WA 1992 (P587), 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 Laverton, WA 1992 (P587), radiometric line data, AWAGS levelled were acquired in 1992 by the WA Government, and consisted of 10225 line-kilometres of data at 400m line spacing and 60m 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.

Paterson North, WA, 2005 (P1091), 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.

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 GSSA Torrens ReducedToPole 1stverticalderivative grid geodetic is the first vertical derivative of the TMI RTP grid of the Torrens Airborne Magnetic Radiometric and DEM Survey, SA, 2017 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 2017 by the SA Government, and consisted of 83653 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 Torrens Airborne Magnetic Radiometric and DEM Survey, SA, 2017 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.

L204 South Eastern Mt Isa Deep Crustal Seismic Reflection Survey, QLD 2014.

Geoscience Australia conducted the Southeastern Mt Isa 2D seismic survey in 2014. The survey involved the acquisition of seismic reflection and gravity data along a single traverse (14GA-CF1) 670km long from Longreach through to Four-ways via Winton. The project was a collaboration between Geoscience Australia and the Geological Survey of Queensland with funding from the Queensland Governments Greenfields 2020 Program. The primary objective of the survey was to image the architecture of the southeastern Mount Isa Inlier and northern Galilee and Millungera Basins. As well as understanding the structural control the Cork Fault plays on resources within the region. 
Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 89638

The early geological history of the Proterozoic Mount Isa Inlier, northwestern Queensland: an alternative interpretation: Reply to discussion

Not surprisingly, Derrick and Wilson find much to disagree with in the interpretation of the geological history of the Mount Isa Inlier proposed in my paper (Blake, 1980). Most of the disagreement comes down to differences in opinion of how best to interpret the available evidence, and I hope to show in this reply to their discussion that there still is scope for alternatives to their interpretation.

Geology of the Lawn Hill

These data are a digital representation of information depicted on the printed map of the Lawn Hill 1:250 000 Geological Series produced by AGSO and the Geological Survey of Queensland (GSQ) in 1983.
Data present include geological polygons (litho-stratigraphic units), linear structural features (faults, dykes, folds, trends, lineaments etc), and point features (mines, structural points etc). Polygons have a range of attributes extracted from each individual map including unit name, age and lithological description, while lines and points are feature coded according to the AGSO publication 'Symbols Used On Geological Maps' (BMR 1989). A standard look-up table of AGSO geological codes and associated descriptions is available (see ADDITIONAL METADATA).
The data has gradually evolved from elementary CAD quality data into its present topologically structured GIS format, and hence has many imperfections and inconsistencies. Data has undergone rigorous validation and testing that includes over 80 different tests. See ADDITIONAL METADATA for more information on the data standards used.
