Fitzroy Isogals (P199392), 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 Fitzroy Isogals (P199392) contains a total of 2 point data values acquired at a spacing of None metres. The data is located in WA and were acquired in 1993, under project No. 199392 for Bureau of Mineral Resources (BMR).

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场变化。所采集的数据将通过标准流程进行处理，以确保记录得到的响应仅由地下岩石引起。经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核查，以确保GA发布的最终数据符合使用要求。本次收录的菲茨罗伊等重力线图（Fitzroy Isogals，编号P199392）共包含2个测点数据，测点间距为无（None）米。该数据采集于西澳大利亚州（Western Australia，WA），采集时间为1993年，隶属于澳大利亚矿产资源局（Bureau of Mineral Resources, BMR）编号为199392的项目。
