Keith, Salt Creek Traverses, Gravity (P198161), 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 Keith, Salt Creek Traverses, Gravity (P198161) contains a total of 323 point data values acquired at a spacing between 250 and 450 metres. The data is located in SA and were acquired in 1981, under project No. 198161 for Department of Mines and Energy South Australia (SADME).

重力数据用于测量地球表层下方岩石密度变化所引发的微小重力变化。所采集的原始数据将通过标准流程进行处理，以确保记录得到的响应仅源于地下岩石。经处理得到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地球物理学家开展质量校验，以保障GA发布的最终数据符合使用要求。本数据集为编号P198161的基思-盐溪剖面重力数据（Keith, Salt Creek Traverses, Gravity），共包含323个测点数据，测点间距介于250米至450米之间。该数据集采集于南澳大利亚州（SA），采集工作于1981年开展，隶属于南澳大利亚州矿产与能源部（SADME）编号为198161的项目。
