Mannum-Adelaide Pipeline Traverse, Gravity (P197143), 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 Mannum-Adelaide Pipeline Traverse, Gravity (P197143) contains a total of 44 point data values acquired at a spacing between 500 and 4000 metres. The data is located in SA and were acquired in 1971, under project No. 197143 for Department of Mines and Energy South Australia (SADME).

重力数据用于观测地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据将通过标准流程进行处理，以确保记录得到的响应仅源于地下岩石的影响。经处理后得到的数据集可通过解译，揭示地下地质构造特征。经处理后的数据会由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使用要求。本曼纳姆-阿德莱德管线剖面重力数据集（P197143）共包含44个测点数据，测点间距介于500米至4000米之间。该数据集由南澳大利亚矿产与能源部（Department of Mines and Energy South Australia，简称SADME）于1971年开展的编号为197143的项目采集，采集区域位于南澳大利亚州（South Australia，简称SA）。
