SA Detailed Gravity Survey, 2004A8 (P200458), 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, 2004A8 (P200458) contains a total of 1299 point data values acquired at a spacing between 200 and 275 metres. The data is located in SA and were acquired in 2004, under project No. 200458 for None.

重力数据可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化流程开展处理，以确保记录得到的响应仅由地下岩石所引发。经处理所得数据集可通过解译，揭示地下地质构造特征。该处理后数据将由GA地球物理学家进行质量核查，以保障GA发布的最终数据符合使用需求。本2004A8号（P200458）南澳大利亚（South Australia，简称SA）详细重力调查数据集共计包含1299组测点数据，测点间距介于200米至275米之间。该数据采集于南澳大利亚，完成于2004年，隶属于编号为200458的项目，委托方信息未标注。
