Isogal Gravity by aircraft Australia (P196793), 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 Isogal Gravity by aircraft Australia (P196793) contains a total of 36 point data values acquired at a spacing of None metres. The data is located in ACT, NSW, NT, QLD, SA, TAS, VIC, WA and were acquired in 1967, under project No. 196793 for Bureau of Mineral Resources (BMR).

重力数据用于测量地球表面下方岩石密度变化所引发的微小重力变动。所采集的数据将通过标准化流程开展处理，以确保记录得到的响应仅由地下岩石所引起。经处理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地球物理学家进行质量核查，以确保GA发布的最终数据符合使用要求。本澳大利亚航空采集的等重力线重力数据集（编号P196793）共包含36个测点数据，采样间距未标注。该数据覆盖澳大利亚首都领地（ACT）、新南威尔士州（NSW）、北领地（NT）、昆士兰州（QLD）、南澳大利亚州（SA）、塔斯马尼亚州（TAS）、维多利亚州（VIC）及西澳大利亚州（WA），于1967年为澳大利亚矿产资源局（Bureau of Mineral Resources, BMR）在项目编号196793下采集完成。
