Eucla South West Gravity Survey (P201162), 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 Eucla South West Gravity Survey (P201162) contains a total of 3800 point data values acquired at a spacing of 2500 metres. The data is located in WA and were acquired in 2012, under project No. 201162 for Geological Survey of Western Australia (GSWA).重力数据用于监测地球表面下方岩石密度变化所引发的微小重力场变化。所采集的数据均通过标准处理流程进行加工，以确保所记录的重力响应仅源于地下岩石的密度变化。经处理后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发布的最终数据满足使用要求。本次尤克拉西南重力勘探（项目编号P201162）共包含3800个测点数据，测点间距为2500米。该数据的采集区域位于西澳大利亚州（Western Australia, WA），采集工作于2012年完成，隶属于西澳大利亚州地质调查局（Geological Survey of Western Australia, GSWA）的201162号项目。
