SA Semi-Detailed Gravity Survey 92B1 (P199271), 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 Semi-Detailed Gravity Survey 92B1 (P199271) contains a total of 180 point data values acquired at a spacing of 1000 metres. The data is located in SA and were acquired in 1992, under project No. 199271 for None.

重力数据（Gravity data）测量地球表面下岩石密度变化导致的重力微小变化。采集到的数据通过标准方法处理，以确保记录的响应仅源于地下岩石。处理结果生成的数据集可通过解释揭示地下地质结构。处理后的数据由GA地球物理学家进行质量检查，以确保GA发布的最终数据符合用途需求。
本SA半详细重力测量92B1（P199271）共包含180个点数据值，采集点间距为1000米。数据位于SA境内，于1992年在项目编号199271下采集，无特定用途说明。
