The Granites Mt Solitaire Highland Rocks Mt Theo potassium grid

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 0.001 degrees (approximately 100m) and shows potassium element concentration of the The Granites, Mt Solitaire, Highland Rocks, Mt Theo, NT, 1993 in units of percent (or %). The data used to produce this grid was acquired in 1993 by the NT Government, and consisted of 108984 line-kilometres of data at 500m line spacing and 90m terrain clearance.
