SA Detailed Gravity Survey 91B6 (P199176), 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 91B6 (P199176) contains a total of 36 point data values acquired at a spacing between 50 and 100 metres. The data is located in SA and were acquired in 1991, under project No. 199176 for None.

重力数据用于测量地球表面下方岩石密度变化所引发的微小重力变化。采集所得数据将通过标准流程开展处理，以确保所记录的响应仅由地下岩石产生。经处理得到的数据集可通过解译揭示地下地质构造。经澳大利亚地质调查局（GA）地球物理学家进行质量核查，以确保GA发布的最终数据符合使用要求。本次南澳州（South Australia）91B6号详细重力测量项目（编号P199176）共包含36个测点数据，测点间距介于50至100米之间。该数据集采集区域位于南澳州，于1991年完成采集，隶属于编号为199176的项目，委托方信息未载明。
