Arltunga Nappe Detailed Gravity (P197308), 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 Arltunga Nappe Detailed Gravity (P197308) contains a total of 213 point data values acquired at a spacing of 1000 metres. The data is located in NT and were acquired in 1973, under project No. 197308 for Bureau of Mineral Resources (BMR).

重力数据（Gravity data）用于测量地球地表下方岩石密度变化引发的微小重力变化。所采集的数据将通过标准流程处理，以确保记录的重力响应仅源于地下岩石的影响。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检查，以确保GA发布的最终数据符合使用要求。本阿尔通加推覆体详细重力数据集（Arltunga Nappe Detailed Gravity, P197308）共包含213个测点数据，测点间距为1000米。该数据集的采集区域位于北领地（NT），于1973年由矿产资源局（Bureau of Mineral Resources, BMR）以项目编号197308立项采集。
