Stuart Shelf 86O0 (P198680), 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 86O0 (P198680) contains a total of 743 point data values acquired at a spacing between 1000 and 2000 metres. The data is located in SA and were acquired in 1986, under project No. 198680 for Department of Minerals and Energy (Victoria).

重力数据可反映地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据均通过标准化流程处理，以确保记录得到的响应仅来源于地下岩石。经处理得到的数据集可通过解译揭示地下地质结构。处理后的数据会由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86O0（编号P198680）数据集共计包含743个测点数据，测点间距介于1000米至2000米之间。该数据的采集点位位于SA，于1986年依托维多利亚州矿产与能源部编号为198680的项目完成采集。
