SA Detailed Gravity Survey, 1995A6 (P199566), 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, 1995A6 (P199566) contains a total of 556 point data values acquired at a spacing between 40 and 200 metres. The data is located in SA and were acquired in 1995, under project No. 199566 for None.

重力数据用于表征地球表层下方岩石密度变化引发的微小重力场变化。所采集的数据将通过标准化处理流程进行处理，以确保记录得到的响应仅源自地下岩石的影响。经处理得到的数据集可通过解译，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查，以确保GA发布的最终数据符合使用要求。本次1995A6版南澳大利亚（South Australia）详细重力测量项目（编号P199566）共包含556组测点数据，测点间距介于40米至200米之间。该数据采集工作于1995年在SA境内开展，所属项目编号为199566，委托方信息为空（None）。
