Grid Gravity Survey SA 93E8 (P199358), 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 Grid Gravity Survey SA 93E8 (P199358) contains a total of 206 point data values acquired at a spacing between 250 and 1000 metres. The data is located in SA and were acquired in 1993, under project No. 199358 for None.

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。所采集的数据将采用标准流程进行处理，以确保记录得到的响应仅由地下岩石引起。经处理得到的数据集可通过解译，揭示地下地质构造。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发布的最终数据符合使用要求。本次网格重力测量SA 93E8（P199358）共包含206个测点数据，测点间距介于250米至1000米之间。本次数据采集区域位于SA境内，采集工作于1993年依托项目编号199358完成，相关工作无委托方。
