Keith Anomaly, Tintinara Traverse, Gravity Survey (1979O2) (P197942), 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 Anomaly, Tintinara Traverse, Gravity Survey (1979O2) (P197942) contains a total of 32 point data values acquired at a spacing of 200 metres. The data is located in SA and were acquired in 1979, under project No. 197942 for BHP Group Ltd.

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场变化。所采集的数据将通过标准化处理流程进行质控，以确保记录得到的响应仅由地下岩石引起。经处理得到的数据集可通过地质解译，揭示地下地质构造特征。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发布的最终数据满足使用需求。本次基思异常（Keith Anomaly）、廷蒂纳测线（Tintinara Traverse）重力测量项目（1979O2）（编号P197942）共计包含32组测点数据，测点间距为200米。该数据采集点位位于南澳大利亚州（South Australia，SA），采集工作于1979年实施，隶属于必和必拓集团有限公司（BHP Group Ltd.）的197942号项目。
