Colac detailed gravity (P199043), gravity point data

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 Colac detailed gravity (P199043) contains a total of 119 point data values acquired at a spacing of 200 metres. The data is located in VIC and were acquired in 1990, under project No. 199043 for Department of Minerals and Energy (Victoria).
