GSWA Perth Basin North Thorium 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.
This radiometric thorium grid has a cell size of 0.00083 degrees (approximately 87m) and shows thorium element concentration of the Perth Basin North, WA, 2011 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2011 by the WA Government, and consisted of 93199 line-kilometres of data at 400m line spacing and 60m terrain clearance.

- Statement
- 
                                This GSWA Perth Basin North Thorium Grid Geodetic is an airborne-derived radiometric thorium grid for the Perth Basin North, WA, 2011. The survey was acquired under the project No. 1242 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 87m). A total of 93199 line-kilometres of data at a line spacing of 400m and 60m terrain clearance were acquired to produce this grid. This radiometric thorium grid shows thorium element concentration of the Perth Basin North, WA, 2011 in units of parts per million (or ppm). Noise-adjusted singular value decomposition (NASVD) has been applied to the data. NASVD is a spectral component analysis procedure for the removal of noise from gamma-ray spectra. Details of the specifications of individual airborne surveys can be found in the Fourteenth Edition of the Index of Airborne Geophysical Surveys (Percival, 2014). This Index is also available online at http://pid.geoscience.gov.au/dataset/79134.
