SA Gravity Survey 2003A12 (P200342), 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 2003A12 (P200342) contains a total of 1076 point data values acquired at a spacing between 800 and 1500 metres. The data is located in SA and were acquired in 2003, under project No. 200342 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。所采集的数据均经标准化流程处理，以确保记录的响应仅源于地下岩石。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2003A12号SA重力测量（P200342）共包含1076个测点数据值，测点间距介于800米至1500米之间。该数据集采集于SA境内，采集工作于2003年完成，隶属于编号为200342的项目，无明确委托方。
