Burra Region Gravity (P196770), 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 Burra Region Gravity (P196770) contains a total of 58 point data values acquired at a spacing between 750 and 1750 metres. The data is located in SA and were acquired in 1967, under project No. 196770 for Department of Mines and Energy South Australia (SADME).

重力数据用于捕捉地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据将通过标准化流程处理，以确保记录得到的重力响应仅源于地下岩石的影响。经处理得到的数据集可通过解译揭示地下地质构造。处理后的数据将由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用需求。本次布拉地区重力数据集（P196770）共包含58个测点数据，测点间距介于750米至1750米之间。该数据采集区域位于南澳（SA），由南澳州矿产与能源部（Department of Mines and Energy South Australia, SADME）下属的196770号项目于1967年完成采集。
