Stuart Shelf (P198076), 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 (P198076) contains a total of 664 point data values acquired at a spacing between 100 and 500 metres. The data is located in SA and were acquired in 1980, under project No. 198076 for Department of Minerals and Energy (Victoria).重力数据用于观测地球表层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开展处理，以确保记录得到的响应仅源自地下岩石。经处理后的数据集可通过解译，用以揭示地下地质构造。经处理的数据将由GA地球物理学家进行质量核验，以确保GA发布的最终数据符合使用要求。本数据集为斯图尔特陆架（Stuart Shelf，编号P198076），共包含664个测点数据，测点间距介于100米至500米之间。该数据集采集区域位于SA地区，采集工作于1980年开展，隶属于维多利亚州矿产与能源部编号为198076的项目。
