Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Quirindi Gravity (P196831) contains a total of 919 point data values acquired at a spacing between 500 and 1800 metres. The data is located in NSW and were acquired in 1968, under project No. 196831 for Alliance Oil Development NL.
