NT Road Surveys 1987-1997 Musgrave Block (P199482), 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 (P199482) contains a total of 214 point data values acquired at a spacing between 200 and 1000 metres. The data is located in NT and were acquired in 1994, under project No. 199482 for Northern Territory of Australia (Northern Territory Geological Survey).

重力数据用于测量地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据将通过标准化流程进行处理，以确保记录的响应仅来源于地下岩石。经处理后得到的数据集可通过解译，用以揭示地下地质构造。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年北领地道路测量穆尔格雷夫地块（P199482），共包含214个测点数据，测点间距介于200米至1000米之间。该数据的采集区域为北领地（NT），于1994年依托澳大利亚北领地地质调查局编号为199482的项目完成采集。
