Sir Samuel Infill Gravity (P199408), 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 Sir Samuel Infill Gravity (P199408) contains a total of 57 point data values acquired at a spacing of 1000 metres. The data is located in WA and were acquired in 1994, under project No. 199408 for Australian Geological Survey Organisation (AGSO).

重力数据用于表征地球表层下方岩石密度变化引发的微小重力场变化。所采集的原始数据将采用标准化方法进行处理，以确保记录的重力响应仅源于地下岩石的影响。经处理得到的数据集可通过解译分析，用以揭示地下地质构造。经处理后的数据将由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用要求。本数据集为塞缪尔爵士加密重力数据集（编号P199408），共包含57个测点数据，测点间距为1000米。该数据集的采集点位位于西澳大利亚州（Western Australia, WA），于1994年为澳大利亚地质调查组织（Australian Geological Survey Organisation, AGSO）的199408号项目所采集。
