SA Gravity Survey 1986O2 (P198652), 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 1986O2 (P198652) contains a total of 141 point data values acquired at a spacing of 750 metres. The data is located in SA and were acquired in 1986, under project No. 198652 for None.

重力数据用于表征地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据均经标准流程处理，以确保记录的重力响应仅源于地下岩石的影响。经处理得到的数据集可通过解译，用以揭示地下地质构造。经处理后的数据由澳大利亚地质调查局（Geoscience Australia，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1986O2南澳重力测量项目（编号P198652）共包含141个测点数据，测点间距为750米。该数据的采集区域位于南澳大利亚州（South Australia），完成于1986年，隶属于编号为198652的项目，无特定委托方。
