West Murchison Gravity Survey (P201260), 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 West Murchison Gravity Survey (P201260) contains a total of 11816 point data values acquired at a spacing of 2500 metres. The data is located in WA and were acquired in 2012, under project No. 201260 for None.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行业标准流程进行处理，以确保记录得到的响应仅由地下岩石的影响所致。经处理得到的数据集可通过解译，用以揭示地下地质构造。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。本次西默奇森重力调查（项目编号：P201260）共包含11816个测点数据，测点间距为2500米。该数据采集工作于2012年开展，对应项目编号为201260，采集区域位于WA州，无特定委托方。
