Gravity Survey (P198361), 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 (P198361) contains a total of 51 point data values acquired at a spacing between 1100 and 100 metres. The data is located in SA and were acquired in 1983, under project No. 198361 for None.

重力数据用于测量地球表层下方岩石密度变化所引发的微小重力变化。所采集的原始数据将通过标准化流程进行处理，以确保记录的重力响应仅源于地下岩石的影响。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。处理完成的数据将由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。本次重力测量项目（P198361）共计包含51个测点数据，测点间距介于1100米至100米之间。本次数据采集区域位于SA，采集工作于1983年实施，隶属于编号为198361的项目，委托方信息无记录。
