SA Detailed Gravity Survey 92B4 (P199274), 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 92B4 (P199274) contains a total of 156 point data values acquired at a spacing between 100 and 500 metres. The data is located in SA and were acquired in 1992, under project No. 199274 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动。所采集的数据经标准流程处理，以确保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）详细重力测量项目92B4（编号P199274）共包含156组测点数据，测点间距介于100米至500米之间。该数据采集于1992年，采集地点位于南澳大利亚，隶属于编号为199274的项目，委托方信息未标注。
