SA Gravity Survey 1994A1 (P199443), 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 Gravity Survey 1994A1 (P199443) contains a total of 678 point data values acquired at a spacing between 100 and 3800 metres. The data is located in SA and were acquired in 1994, under project No. 199443 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。所采集的数据将通过标准化处理流程进行加工，以确保所记录的响应仅由地下岩石引起。经处理得到的数据集可通过地质解译揭示地下地质构造。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。本次南澳大利亚（South Australia，简称SA）重力测量1994A1（编号P199443）共包含678个测点数据，测点间距介于100米至3800米之间。该数据采集于SA地区，于1994年完成，隶属于编号为199443的项目，委托方信息未标注。
