Morton Craig Gravity Survey (P200160), 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 Morton Craig Gravity Survey (P200160) contains a total of 431 point data values acquired at a spacing between 1000 and 2000 metres. The data is located in WA and were acquired in 2001, under project No. 200160 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引发的微小重力场变化。所采集的数据将通过标准化处理流程进行校正，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地质解译，揭示地下地质构造特征。经处理的数据将由西澳大利亚地质调查局（Geological Survey of Western Australia，简称GSWA）的地球物理学家开展质量核查，以确保该局发布的最终数据符合使用要求。本次莫顿·克雷格重力测量项目（编号P200160）共包含431个测点数据，测点间距介于1000米至2000米之间。该数据集采集于西澳大利亚州（Western Australia，简称WA），采集时间为2001年，隶属于西澳大利亚地质调查局编号为200160的项目。
