Isogal Excentre Broome WA, Gravity (P196892), 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 Excentre Broome WA, Gravity (P196892) contains a total of 2 point data values acquired at a spacing of 1000 metres. The data is located in WA and were acquired in 1968, under project No. 196892 for Bureau of Mineral Resources (BMR).

重力数据用于表征地球表层下方岩石密度变化所引发的微小重力场变化。所采集的原始数据将通过标准化流程进行处理，以确保记录的响应仅由地下岩石的密度变化引起。经处理得到的数据集可通过专业解译，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。本次发布的西澳大利亚州布鲁姆外港伊索加尔（Isogal）重力数据集（P196892）共包含2个测点数据，测点间距为1000米。该数据集采集区域位于西澳大利亚州，采集时间为1968年，隶属于矿产资源局（Bureau of Mineral Resources, BMR）编号196892的项目。
