McArthur Basin Gravity (P198011), 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 McArthur Basin Gravity (P198011) contains a total of 865 point data values acquired at a spacing of 500 metres. The data is located in NT and were acquired in 1980, under project No. 198011 for Bureau of Mineral Resources (BMR).

重力数据可量化地球表层下方岩石密度变化所引发的微小重力变化。所采集的数据需通过标准处理流程进行校正，以确保记录得到的实测响应仅源于地下岩石的影响。经处理后生成的数据集可通过解译揭示地下地质构造特征。经处理的数据需由GA(Geoscience Australia)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。本麦克阿瑟盆地重力数据集（P198011）共计包含865组测点数据，测点间距为500米。该数据集的采集点位位于北领地(NT, Northern Territory)，于1980年为矿产资源局(Bureau of Mineral Resources, BMR)的198011号项目采集完成。
