Canberra Gravity (Weston Creek) (P197024), 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 Canberra Gravity (Weston Creek) (P197024) contains a total of 988 point data values acquired at a spacing between 50 and 350 metres. The data is located in ACT and were acquired in 1970, under project No. 197024 for Bureau of Mineral Resources (BMR).

重力数据用于测量因地球表层下方岩石密度变化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。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发布的最终数据符合使用需求。本次的堪培拉重力（韦斯顿溪）数据集（编号P197024）共计包含988个测点数据，测点间距介于50米至350米之间。该数据集的采集区域为澳大利亚首都领地（Australian Capital Territory, ACT），采集工作于1970年开展，对应矿产资源局（Bureau of Mineral Resources, BMR）编号为197024的项目。
