Ashby, Coondappie Traverses, Gravity, 1971E7 (P197147), 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 Ashby, Coondappie Traverses, Gravity, 1971E7 (P197147) contains a total of 457 point data values acquired at a spacing of 60 metres. The data is located in SA and were acquired in 1971, under project No. 197147 for Department of Mines and Energy South Australia (SADME).

重力数据用于表征地球表层下方岩石密度变化引发的微小重力场扰动。采集所得数据将通过标准化流程开展处理，以确保记录的重力响应仅源于地下岩石介质。经处理得到的数据集可通过解译，揭示地下地质构造特征。经处理的数据将由GA地球物理学家进行质量核验，以保障GA发布的最终数据符合应用要求。
