SA Detailed Gravity Survey 91B4 (P199174), 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 91B4 (P199174) contains a total of 133 point data values acquired at a spacing between 100 and 1000 metres. The data is located in SA and were acquired in 1991, under project No. 199174 for None.

重力数据用于监测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流程进行处理，以确保记录的响应仅由地下岩石引发。经处理得到的数据集可用于解译，以揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量检查，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）详细重力测量项目91B4（编号P199174）共包含133组测点数据，测点间距介于100米至1000米之间。本次测量数据采集于SA区域，完成于1991年，隶属于编号199174的项目，相关委托方信息未注明。
