Gravity Survey SA 93A8 (P199366), 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 93A8 (P199366) contains a total of 145 point data values acquired at a spacing of 100 metres. The data is located in SA and were acquired in 1993, under project No. 199366 for None.

重力数据可用于测量地球表面下方岩石密度变化引发的微小重力场变化。所采集的原始数据将通过标准处理流程进行加工，以确保记录得到的重力响应仅源自地下岩石。经处理后得到的数据集可通过地质解译，揭示地下地质构造特征。经处理的数据将由GA地球物理学家开展质量核验，以保障GA发布的最终数据符合实际使用要求。本次重力测量项目SA 93A8（编号P199366）共计包含145个测点数据，测点间距为100米。该数据集采集于SA地区，采集时间为1993年，隶属于项目编号199366，委托方信息未标注。
