Bowmans Detailed Gravity (P198162), 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 Bowmans Detailed Gravity (P198162) contains a total of 2060 point data values acquired at a spacing of 500 metres. The data is located in SA and were acquired in 1981, under project No. 198162 for Department of Mines and Energy South Australia (SADME).

重力数据用于监测地球表层下方岩石密度变化所引发的微小重力场变化。所采集的原始数据将通过标准化流程进行处理，以确保记录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。处理后的数据需由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要求。本鲍曼斯详细重力数据集（编号P198162）共计包含2060个测点数据，测点间距为500米。该数据集的测点分布于南澳州（South Australia），采集工作于1981年开展，由南澳州矿产与能源部（South Australia Department of Mines and Energy，SADME）立项的编号198162项目实施采集。
