Narromine regional infill gravity (P199403), 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 Narromine regional infill gravity (P199403) contains a total of 358 point data values acquired at a spacing of 4000 metres. The data is located in NSW and were acquired in 1994, under project No. 199403 for Australian Geological Survey Organisation (AGSO); Geological Survey of New South Wales (GSNSW).

重力数据用于测量地球地表下方岩石密度变化所引发的微小重力场变化。所采集的原始数据将通过标准化流程进行处理，以确保记录的重力响应仅由地下岩石的密度变化引起。经处理后生成的数据集可通过解译揭示地下地质构造特征。经处理后的重力数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据符合使用要求。本次的纳罗明区域加密重力数据集（P199403）共计包含358个测点数据，测点布设间距为4000米。该数据集采集区域位于新南威尔士州（New South Wales, NSW），数据采集工作完成于1994年，相关项目编号为199403，由澳大利亚地质调查局（Australian Geological Survey Organisation, AGSO）与新南威尔士州地质调查局（Geological Survey of New South Wales, GSNSW）联合实施。
