This GSNSW Exploration NSW Area D Surat Basin thorium grid geodetic is an airborne-derived radiometric thorium window countrate grid for the NSW DMR, Discovery 2000,1994-95, Area D, Surat Basin survey. 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 thorium (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 GSNSW Exploration NSW Area D Surat Basin thorium grid geodetic has a cell size of 0.00072 degrees (approximately 75m). The data are in units of counts per second (or cps). The data used to produce this grid was acquired in 1995 by the NSW Government, and consisted of 117000 line-kilometres of data at 400m line spacing and 80m terrain clearance.
