Dataset: Radiometric uranium equivalent grid of Darling Basin (Cobham Lake, White Cliffs), NSW, 1981 survey


Description

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 uranium grid has a cell size of 0.008 degrees (approximately 830m) and shows uranium element concentration of the Darling Basin (Cobham Lake, White Cliffs), NSW, 1981 survey. The data used to produce this grid was acquired in 1981 by the NSW Government, and consisted of 14751 line-kilometres of data at 3000m line spacing and 150m terrain clearance.
