Dandaloo Detailed Gravity (P199163), 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 Dandaloo Detailed Gravity (P199163) contains a total of 1355 point data values acquired at a spacing between 200 and 1000 metres. The data is located in NSW and were acquired in 1991, under project No. 199163 for Newcrest Mining Ltd.重力数据用于监测地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据将采用标准处理流程进行加工，以确保记录得到的重力响应仅由地下岩石引起。处理后得到的数据集可通过解译，揭示地下地质构造。由GA地球物理学家对处理后的数据开展质量核查，以确保GA发布的最终数据满足使用需求。本次丹达卢详细重力数据集（P199163）共包含1355个测点数据，测点间距介于200米至1000米之间。该数据集采集于新南威尔士州（NSW），于1991年由新克雷斯特矿业有限公司（Newcrest Mining Ltd）以项目编号199163完成采集。
