Yilgarn Seismic Lines - Line 5 (P199915), 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 Yilgarn Seismic Lines - Line 5 (P199915) contains a total of 84 point data values acquired at a spacing of 280 metres. The data is located in WA and were acquired in 1999, under project No. 199915 for Australian Geological Survey Organisation (AGSO).

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。所采集的数据将通过标准流程进行处理，以确保记录得到的响应仅源于地下岩石的影响。经处理后得到的数据集可用于解译，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要求。本次数据集为伊尔干地震测线5号线（P199915），共包含84个点位数据，采集间距为280米。该数据采集点位位于西澳大利亚州（Western Australia, WA），于1999年为澳大利亚地质调查组织（Australian Geological Survey Organisation, AGSO）实施的编号199915项目中采集完成。
