Braidwood Gravity Survey 2006 (P200620), 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 Braidwood Gravity Survey 2006 (P200620) contains a total of 917 point data values acquired at a spacing between 1000 and 2000 metres. The data is located in NSW and were acquired in 2006, under project No. 200620 for Geological Survey of New South Wales (GSNSW).

重力数据用于测量地球表面下方岩石密度变化引发的微小重力变化。所采集的数据将采用标准方法进行处理，以确保所记录的响应仅由地下岩石引起。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需求。本次2006年布雷德伍德重力测量项目（P200620）共包含917个测点数据，测点间距介于1000米至2000米之间。该数据采集于新南威尔士州（NSW），于2006年由新南威尔士州地质调查局（Geological Survey of New South Wales，GSNSW）以编号200620的项目完成采集。
