Gravity Survey (P198176), 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 (P198176) contains a total of 306 point data values acquired at a spacing of 200 metres. The data is located in SA and were acquired in 1981, under project No. 198176 for None.

重力数据用于量化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。采集所得数据将通过标准流程开展处理，以确保记录得到的响应仅由地下岩石的影响所产生。经处理后生成的数据集可通过解译，用以揭示地下地质构造特征。经处理的数据将由GA地球物理学家进行质量核验，以确保GA发布的最终数据满足使用需求。本次重力测量（Gravity Survey，编号P198176）共计包含306组测点数据，采集间距为200米。本次数据采集区域位于SA地区，完成于1981年，隶属于编号198176的项目，委托方信息未标注。
