Duketon Infill Gravity, 1994, WA (P199406), 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 Duketon Infill Gravity, 1994, WA (P199406) contains a total of 693 point data values acquired at a spacing between 400 and 4000 metres. The data is located in WA and were acquired in 1994, under project No. 199406 for Australian Geological Survey Organisation (AGSO); Geological Survey of Western Australia (GSWA).

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动。所采集的数据将通过标准化处理流程开展质控校准，以确保记录得到的响应仅源于地下岩石的影响。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发布的最终数据符合应用需求。本数据集为1994年西澳大利亚州（Western Australia）的达卡顿加密重力测量数据（编号P199406），共包含693个测点数据，测点间距介于400米至4000米之间。该数据采集区域位于西澳大利亚州，于1994年由澳大利亚地质调查组织（Australian Geological Survey Organisation, AGSO）与西澳大利亚州地质调查局（Geological Survey of Western Australia, GSWA）作为项目199406的成果完成采集。
