Geophysical Acquisition & Processing Section

Abstract

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 Ballarat - St Arnaud Region Gravity (P198244) contains a total of 1633 point data values acquired at a spacing between 100 and 400 metres. The data is located in VIC and were acquired in 1982, under project No. 198244 for Department of Minerals and Energy (Victoria).

Lineage

This Ballarat - St Arnaud Region Gravity (P198244), gravity point data contains ground gravity point data for the Ballarat - St Arnaud Region Gravity (P198244) survey acquired for Department of Minerals and Energy (Victoria). This dataset contains a total of 1633 point data values. The data is located in VIC and were acquired in 1982. The point located data were collected in irregular traverses layout at a station spacing between 100 and 400 metres. Terrain corrections were calculated using the INTREPID Geophysics software package. The processed data are checked by GA geophysicists using standard methods for assessing quality to ensure that the final data are fit-for-purpose. All data are provided in EPSG:4283 coordinates, Australian Height Datum (AHD) and gravity datum of AAGD07. The units are degrees, meters, and micrometres per second squared, respectively.
