Waigen Sub-basin Gravity (P199864), 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 Waigen Sub-basin Gravity (P199864) contains a total of 1372 point data values acquired at a spacing between 2000 and 3000 metres. The data is located in SA, WA and were acquired in 1998, under project No. 199864 for Geological Survey of Western Australia (GSWA).重力数据用于测量地球表层下方岩石密度变化引发的微小重力变动。所采集的原始数据将通过标准化流程进行处理，以确保记录得到的响应仅源于地下岩石。经处理后生成的数据集可通过解译揭示地下地质构造。处理完成的重力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验，确保该局发布的最终数据符合使用需求。本次外恩次盆重力数据集（Waigen Sub-basin Gravity，编号P199864）共计包含1372个测点数据，测点间距介于2000米至3000米之间。该数据集的采集区域覆盖南澳大利亚州（South Australia，简称SA）与西澳大利亚州（Western Australia，简称WA），采集工作于1998年开展，隶属于GSWA编号为199864的项目。
