Torrens - Andamooka Region Gravity (P196855), 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 - Andamooka Region Gravity (P196855) contains a total of 384 point data values acquired at a spacing between 3000 and 7000 metres. The data is located in SA and were acquired in 1968, under project No. 196855 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场异常。所采集的原始数据将通过标准化流程进行处理，以确保记录得到的响应仅源于地下岩石的密度效应。经处理得到的数据集可通过解译，用以揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据满足使用需求。本托伦斯-安达穆卡地区重力数据集（编号P196855）共计包含384个测点数据，测点间距介于3000米至7000米之间。该数据集的采集区域位于南澳大利亚州（South Australia），并于1968年由南澳大利亚矿产与能源部（Department of Mines and Energy South Australia, SADME）以编号196855的项目完成采集。
