North Western Victoria Gravity (P195609), 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 North Western Victoria Gravity (P195609) contains a total of 192 point data values acquired at a spacing between 5000 and 10000 metres. The data is located in VIC and were acquired in 1956, under project No. 195609 for Bureau of Mineral Resources (BMR).

重力数据用于表征地球地下岩石密度变化所引发的微小重力场变化。采集所得数据将通过标准化处理流程开展处理，以确保记录的重力响应仅源于地下岩石的影响。经处理得到的数据集可通过解译，揭示地下地质构造特征。处理后的数据将由GA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。本维多利亚州西北部重力数据集（P195609）共计包含192个测点数据，测点间距介于5000米至10000米之间。该数据集的采集区域为维多利亚州（VIC），外业工作完成于1956年，隶属于澳大利亚矿产资源局（Bureau of Mineral Resources, BMR）编号为195609的项目。
