Gravity Survey SA 78P1 (P197876), 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 Gravity Survey SA 78P1 (P197876) contains a total of 623 point data values acquired at a spacing between 100 and 2000 metres. The data is located in SA and were acquired in 1978, under project No. 197876 for None.

重力数据用于测量地球地表下方岩石密度变化所引发的微小重力变化。所采集的数据将通过标准处理流程进行校准与加工，以确保记录得到的响应仅由地下岩石引起。经处理后的数据集可通过地质解译，揭示地下的地质构造特征。经处理的数据将由GA地球物理学家开展质量核验，以确保GA对外发布的最终数据满足使用需求。本次重力测量项目SA 78P1（编号P197876）共包含623组测点数据，测点间距介于100米至2000米之间。该数据采集于南澳大利亚（SA），采集年份为1978年，隶属于编号197876的项目，委托方信息未标注。
