Fraser Range - Zanthus Geochem-Gravity (P199863), 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 Fraser Range - Zanthus Geochem-Gravity (P199863) contains a total of 1243 point data values acquired at a spacing of 4000 metres. The data is located in WA and were acquired in 1998, under project No. 199863 for Australian Geological Survey Organisation (AGSO); Geological Survey of Western Australia (GSWA).

重力数据用于观测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流程进行处理，以确保记录得到的重力响应仅来源于地下岩石。经处理得到的数据集可通过解译揭示地下地质构造。经处理后的数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据满足使用需求。本弗雷泽山脉-赞瑟斯地球化学-重力数据集（编号P199863）共计包含1243个测点数据，测点布设间距为4000米。该数据集采集于西澳大利亚州，完成于1998年，隶属于为澳大利亚地质调查局（Australian Geological Survey Organisation, AGSO）与西澳大利亚地质调查局（Geological Survey of Western Australia, GSWA）实施的编号为199863的项目。
