Byro Sub-basin Gravity (P199761), 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 Byro Sub-basin Gravity (P199761) contains a total of 970 point data values acquired at a spacing between 1000 and 2000 metres. The data is located in WA and were acquired in 1997, under project No. 199761 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所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加工，以确保记录的响应仅由地下岩石引起。经处理得到的数据集可通过解译，用以揭示地下地质构造。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需求。本次发布的拜罗次盆地重力数据集（P199761）共计包含970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（WA），采集工作于1997年开展，隶属于西澳大利亚地质调查局（Geological Survey of Western Australia，简称GSWA）编号为199761的项目。
