GSWA Newdegate Ravensthorpe Bremer Bay Merge percent Potassium 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 potassium grid has a cell size of 0.00083 degrees (approximately 85m) and shows potassium element concentration of the Newdegate-Ravensthorpe-Bremer Bay merge, 1999-2005 in units of percent (or %). The data used to produce this grid was acquired in 1999 by the WA Government, and consisted of 93624 line-kilometres of data at a line spacing between 300m and 400m, and 70m terrain clearance.

Statement

This GSWA Newdegate Ravensthorpe Bremer Bay Merge percent Potassium Grid Geodetic is an airborne-derived radiometric potassium grid for the Newdegate-Ravensthorpe-Bremer Bay merge, 1999-2005. The survey was acquired under the project No. 1332 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 85m). A total of 93624 line-kilometres of data at a line spacing between 300m and 400m, and 70m terrain clearance were acquired to produce this grid. This radiometric potassium grid shows potassium element concentration of the Newdegate-Ravensthorpe-Bremer Bay merge, 1999-2005 in units of percent (or %). 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.
