SA Detailed Gravity Survey 1995A4 (P199574), 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 1995A4 (P199574) contains a total of 1794 point data values acquired at a spacing between 100 and 1000 metres. The data is located in SA and were acquired in 1995, under project No. 199574 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化。所采集的数据将通过标准方法进行处理，以确保记录的重力响应仅由地下岩石引发。经处理得到的数据集可通过解译以揭示地下地质构造。处理后的数据将由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SA详细重力测量1995A4（P199574）数据集共计包含1794个测点数据，测点间距介于100米至1000米之间。该数据集采集区域位于SA，采集工作于1995年开展，对应项目编号为199574，委托方信息未标注。
