Virginia Fault - SADM Detailed Gravity (P196769), 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 Virginia Fault - SADM Detailed Gravity (P196769) contains a total of 322 point data values acquired at a spacing between 30 and 100 metres. The data is located in SA and were acquired in 1967, under project No. 196769 for Department of Mines and Energy South Australia (SADME).

重力数据用于测量地球表层下方岩石密度变化所引发的微小重力变化。所采集的数据需经标准流程处理，以确保所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发布的最终数据满足实际应用需求。本弗吉尼亚断层-SADM高精度重力数据集（编号P196769）共包含322个测点数据，测点间距介于30米至100米之间。该数据集的采集区域位于南澳大利亚州（SA），于1967年完成采集工作，隶属于南澳大利亚州矿产与能源部（SADME）编号为196769的项目。
