Nyngan, Narromine, Forbes Region Gravity (P198531), 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 Nyngan, Narromine, Forbes Region Gravity (P198531) contains a total of 1319 point data values acquired at a spacing between 2000 and 6000 metres. The data is located in NSW and were acquired in 1985, under project No. 198531 for Department of Mines (New South Wales).

重力数据用于监测地球表层下方岩石密度变化所引发的微小重力变化。所采集的数据将通过标准化流程进行处理，以确保记录的重力响应仅由地下岩石所致。经处理得到的数据集可通过解译，用以揭示地下地质构造。经处理后的数据将由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。本宁根、纳罗明、福布斯地区重力数据集（P198531）共计包含1319个测点数据，测点间距介于2000米至6000米之间。该数据集采集于新南威尔士州（NSW），采集时间为1985年，隶属于新南威尔士州矿产部编号为198531的项目。
