Arrowie Detailed Grid (Copley), Gravity (P198260), 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 Arrowie Detailed Grid (Copley), Gravity (P198260) contains a total of 915 point data values acquired at a spacing between 75 and 300 metres. The data is located in SA and were acquired in 1982, under project No. 198260 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动。采集所得的原始数据将通过标准化流程开展处理，确保记录的重力响应仅源于地下岩石的影响。经处理后生成的数据集可通过解译，揭示地下地质构造特征。处理完成的数据将由GA地球物理学家进行质量核验，以确保GA发布的最终数据满足使用需求。本数据集为阿罗维详细测网（科普利）重力数据（P198260），共计包含915组测点数据，测点间距介于75米至300米之间。该数据集的采集区域位于南澳大利亚州（SA），采集工作于1982年完成，隶属于南澳大利亚州矿产与能源部（Department of Mines and Energy South Australia, SADME）编号为198260的项目。
