SA Detailed Gravity Survey, 2002A22 (P200288), 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 SA Detailed Gravity Survey, 2002A22 (P200288) contains a total of 968 point data values acquired at a spacing between 200 and 400 metres. The data is located in SA and were acquired in 2002, under project No. 200288 for None.

重力数据用于表征地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据将通过标准化流程进行处理，以确保记录的响应仅源于地下岩石的影响。经处理后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查，以确保GA发布的最终数据符合使用要求。本次编号为2002A22（P200288）的南澳（SA）详细重力测量数据集共计包含968个测点数据，测点间距介于200至400米之间。该数据采集点位位于南澳（SA），采集工作于2002年依托项目编号200288完成，委托方信息未标注。
