Torrens Lineament - SADM Road Gravity (P196382), 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 Torrens Lineament - SADM Road Gravity (P196382) contains a total of 506 point data values acquired at a spacing between 200 and 400 metres. The data is located in SA and were acquired in 1963, under project No. 196382 for Department of Mines and Energy South Australia (SADME).

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。所采集的数据将通过标准化流程进行处理，确保记录的重力响应仅由地下岩石所引起。经处理得到的数据集可通过地质解译，揭示地下地质构造特征。经处理的数据会由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实际应用需求。本次发布的托伦斯线性构造-SADM道路重力数据集（P196382）共计包含506组测点数据，测点间距介于200米至400米之间。该数据集采集于南澳大利亚州（SA），采集时间为1963年，隶属于南澳大利亚州矿产与能源部（SADME）编号为196382的项目。
