Stuart Shelf (P197722), 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 Stuart Shelf (P197722) contains a total of 800 point data values acquired at a spacing between 100 and 500 metres. The data is located in SA and were acquired in 1977, under project No. 197722 for Department of Minerals and Energy (Victoria).

重力数据用于测量地球表层下方岩石密度变化引发的微小重力变动。所采集的数据将通过标准方法进行处理，以确保所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，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。本斯图尔特陆架（Stuart Shelf，编号P197722）数据集共计包含800个测点数据，测点间距介于100米至500米之间。该数据集采集于南澳大利亚州（SA），采集工作于1977年开展，隶属于维多利亚州矿产与能源部的197722号项目。
