Broken Hill - Isles Gravity (P199422), 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 Broken Hill - Isles Gravity (P199422) contains a total of 6018 point data values acquired at a spacing of 50 metres. The data is located in NSW and were acquired in 1994, under project No. 199422 for CRA Exploration Pty Ltd.

重力数据用于监测地球表层下方岩石密度变化引发的重力场微小变化。所采集的数据均通过标准化流程处理，以确保记录的响应仅来源于地下岩石的重力效应。经处理后得到的数据集可通过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验，以确保GA发布的最终数据符合使用要求。布罗肯希尔-艾尔尔斯重力数据集（P199422）总计包含6018组测点数据，采集间距为50米。该数据集位于新南威尔士州，采集于1994年，对应为CRA Exploration Pty Ltd立项编号199422的项目所获取的数据。
