Colac-Otway Detailed (P198342), 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-Otway Detailed (P198342) contains a total of 406 point data values acquired at a spacing between 35 and 55 metres. The data is located in VIC and were acquired in 1983, under project No. 198342 for Department of Minerals and Energy (Victoria).
