Tumut Gravity (P198030), 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 Tumut Gravity (P198030) contains a total of 46 point data values acquired at a spacing of 500 metres. The data is located in NSW and were acquired in 1980, under project No. 198030 for Australian National University (ANU).

重力数据用于测量地球表面下方岩石密度变化所引发的微小重力变化。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源于地下岩石的影响。经处理后得到的数据集可通过解译，揭示地下地质构造。经处理的数据会由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。本次的图特重力数据集（Tumut Gravity，编号P198030）共包含46个测点数据，测点间距为500米。该数据集采集于新南威尔士州（New South Wales, NSW），采集工作于1980年开展，隶属于为澳大利亚国立大学（Australian National University, ANU）实施的编号198030项目。
