Eastern Lachlan Seismic Gravity traverses (P199707), 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 Eastern Lachlan Seismic Gravity traverses (P199707) contains a total of 370 point data values acquired at a spacing of 300 metres. The data is located in NSW and were acquired in 1997, under project No. 199707 for Australian Geological Survey Organisation (AGSO).

重力数据用于监测地球表层下方岩石密度变化引发的微小重力场变化。所采集的数据将采用标准方法进行处理，以确保记录得到的响应仅由地下岩石引发。经处理得到的数据集可通过地质解译揭示地下地质构造。处理后的数据由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。本次东拉克伦地震重力测线（P199707）共计包含370组测点数据，测点间距为300米。该数据采集于新南威尔士州（New South Wales, NSW），采集时间为1997年，隶属于澳大利亚地质调查局（Australian Geological Survey Organisation, AGSO）编号为199707的项目。
