Savory Basin Gravity (P199561), 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 Savory Basin Gravity (P199561) contains a total of 2495 point data values acquired at a spacing between 2000 and 3000 metres. The data is located in WA and were acquired in 1995, under project No. 199561 for Geological Survey of Western Australia (GSWA).

重力数据用于测量因地球表层下方岩石密度变化引发的微小重力变化。所采集的数据将通过标准流程进行处理，以确保记录的响应仅源于地下岩石的影响。经处理后得到的数据集可通过解译揭示地下地质构造。经处理后的数据将由澳大利亚西部地质调查局（Geological Survey of Western Australia，GSWA）的地球物理学家开展质量核验，以确保该局发布的最终数据符合使用要求。本萨沃里盆地重力数据集（编号P199561）共包含2495个测点数据，测点间距介于2000至3000米之间。该数据集采集于西澳大利亚州，采集工作于1995年开展，隶属于澳大利亚西部地质调查局编号为199561的项目。
