Yilgarn Seismic Lines - Line 2 (P199912), 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 2 (P199912) contains a total of 156 point data values acquired at a spacing of 280 metres. The data is located in WA and were acquired in 1999, under project No. 199912 for Australian Geological Survey Organisation (AGSO).

重力数据用于量化表征地球表层下方岩石密度变化所引发的微小重力扰动。所采集的数据将通过标准化处理流程开展校正，以确保所记录的响应仅由地下岩石的重力效应引起。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GA地球物理学家开展质量核查，以确保GA发布的最终数据满足使用要求。本数据集为伊尔冈地震测线2号（P199912），共包含156个测点数据，测点间距为280米。该数据采集于西澳大利亚州（Western Australia，WA），采集时间为1999年，隶属于澳大利亚地质调查组织（Australian Geological Survey Organisation，AGSO）的199912号项目。
