Stuart Shelf (P197668), 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 (P197668) contains a total of 1039 point data values acquired at a spacing between 100 and 500 metres. The data is located in SA and were acquired in 1976, under project No. 197668 for Department of Minerals and Energy (Victoria).

重力数据可量化表征地球表层下方岩石密度变化所引发的微小重力场变动。所采集的原始数据将通过标准化处理流程开展质控，确保记录得到的响应仅源于地下岩石。经处理后得到的数据集可通过地质解译揭示地下地质构造形态。GA地球物理学家将对处理后的数据开展质量核查，以确保GA发布的最终数据符合使用要求。本次斯特尔特陆架（Stuart Shelf，项目编号P197668）数据集共包含1039个测点数据，测点间距介于100米至500米之间。该数据采集于南澳大利亚（SA），采集工作于1976年由维多利亚州矿产与能源部依托编号为197668的项目完成。
