NT Road Surveys 1987-1997 Musgrave Block (P199682), 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 NT Road Surveys 1987-1997 Musgrave Block (P199682) contains a total of 449 point data values acquired at a spacing between 200 and 1000 metres. The data is located in NT and were acquired in 1996, under project No. 199682 for Northern Territory of Australia (Northern Territory Geological Survey).

重力数据用于监测地球地表下方岩石密度变化所引发的微小重力场变化。所采集的数据均通过标准流程进行处理，以确保记录的响应仅源于地下岩石。经处理得到的数据集可通过解译，揭示地下地质构造。经处理的数据由北领地地质调查局（Northern Territory Geological Survey，简称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。本数据集为1987-1997年北领地（Northern Territory，简称NT）道路测量马斯格雷夫地块项目（P199682），共包含449组测点数据，测点间距介于200米至1000米之间。该数据采集于北领地，完成于1996年，隶属于澳大利亚北领地编号为199682的项目，实施方为北领地地质调查局（Northern Territory Geological Survey）。
