Dubbo regional infill - part 2, Gravity (P199401), 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 Dubbo regional infill - part 2, Gravity (P199401) contains a total of 281 point data values acquired at a spacing between 1500 and 5000 metres. The data is located in NSW and were acquired in 1994, under project No. 199401 for Australian Geological Survey Organisation (AGSO); Geological Survey of New South Wales (GSNSW).

重力数据用于表征地球浅表下方岩石密度变化所引发的微小重力变化。所采集的数据将通过标准流程开展处理，以确保记录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地球物理学家进行质量核验，以确保GA发布的最终数据符合使用要求。本次达博（Dubbo）区域加密测量第二部分——重力测量数据集（编号P199401）共包含281个测点数据，测点间距介于1500米至5000米之间。该数据集采集于新南威尔士州（New South Wales，NSW），采集工作于1994年开展，由澳大利亚地质调查组织（Australian Geological Survey Organisation，AGSO）与新南威尔士州地质调查局（Geological Survey of New South Wales，GSNSW）以项目编号199401实施。
