Barker Region Gravity (P196860), 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 Barker Region Gravity (P196860) contains a total of 212 point data values acquired at a spacing between 3000 and 6000 metres. The data is located in SA and were acquired in 1968, under project No. 196860 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化。采集得到的原始数据将通过标准化方法开展处理，以确保所记录的响应仅源自地下岩石。经处理生成的数据集可通过解译揭示地下地质构造特征。经处理后的数据由GA地球物理学家开展质量核验，以保障GA发布的最终数据满足使用需求。本次巴克地区重力数据集（编号P196860）共计包含212个测点数据，测点布设间距介于3000米至6000米之间。该数据集的采集区域位于南澳大利亚州（SA），野外数据采集工作于1968年开展，隶属于南澳大利亚矿产与能源部（SADME）编号为196860的项目。
