West Wyalong Gravity Along Seismic Lines - Line 3 (P199903), 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 West Wyalong Gravity Along Seismic Lines - Line 3 (P199903) contains a total of 282 point data values acquired at a spacing of 320 metres. The data is located in NSW and were acquired in 1999, under project No. 199903 for Australian Geological Survey Organisation (AGSO).

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变化。所采集的数据将通过标准流程开展处理，以确保记录得到的响应仅源于地下岩石的影响。经处理得到的数据集可通过解译，揭示地下地质构造特征。经处理后的数据会由澳大利亚地球科学局（Geoscience Australia, GA）的地球物理学家进行质量核查，以确保GA对外发布的最终数据符合使用要求。本次西怀龙地震测线沿线重力数据——第3测线（P199903）数据集共包含282个测点数据，测点间距为320米。该数据集采集于新南威尔士州（New South Wales, NSW），采集工作于1999年开展，隶属于澳大利亚地质调查组织（Australian Geological Survey Organisation, AGSO）的199903号项目。
