Ngururrpa Gravity Survey (P201560), 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 Ngururrpa Gravity Survey (P201560) contains a total of 4965 point data values acquired at a spacing of 2500 metres. The data is located in WA and were acquired in 2015, under project No. 201560 for Geological Survey of Western Australia (GSWA).

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扰动。所采集的数据将通过标准处理流程进行校正，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。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Ngururrpa重力调查（P201560）共计包含4965个测点数据，测点间距为2500米。数据采集区域位于西澳大利亚州（Western Australia），相关数据采集工作于2015年开展，隶属于西澳大利亚地质调查局（Geological Survey of Western Australia, GSWA）编号为201560的项目。
