SA Detailed Gravity Survey 99A4 (P199954), 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 99A4 (P199954) contains a total of 204 point data values acquired at a spacing of 800 metres. The data is located in SA and were acquired in 1999, under project No. 199954 for None.

重力数据用于表征地球表面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开展处理，以确保记录得到的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，用以揭示地下地质构造。经处理的数据将由GA地球物理学家进行质量核查，以确保GA发布的最终数据符合使用需求。本次SA详细重力测量99A4（编号P199954）共包含204组测点数据，测点布设间距为800米。该数据采集于SA地区，完成于1999年，对应项目编号为199954，委托方信息无。
