Farina - SADM Road Gravity (P196161), 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 Farina - SADM Road Gravity (P196161) contains a total of 149 point data values acquired at a spacing of 100 metres. The data is located in SA and were acquired in 1961, under project No. 196161 for Department of Mines and Energy South Australia (SADME).

重力数据用于测量地球表面下岩石密度变化引发的重力微小波动。采集所得数据经标准方法处理，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译揭示地下地质结构。GA地球物理学家会对处理后数据进行质量核查，确保GA发布的最终数据满足预期用途。

本Farina-SADM公路重力数据集（P196161）共包含149个点数据值，采集间距为100米。数据位于南澳大利亚州（SA），于1961年采集，隶属于为南澳大利亚州矿产与能源部（Department of Mines and Energy South Australia，SADME）开展的196161号项目。
