Goulburn Infill Gravity (P199705), 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 Goulburn Infill Gravity (P199705) contains a total of 969 point data values acquired at a spacing between 2000 and 4000 metres. The data is located in NSW and were acquired in 1997, under project No. 199705 for Australian Geological Survey Organisation (AGSO); Geological Survey of New South Wales (GSNSW).

重力数据用于捕捉因地球地表下方岩石密度变化引发的微小重力变动。所采集的数据将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的影响。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发布的最终数据满足使用需求。本次古尔本填充重力数据集（Goulburn Infill Gravity，编号P199705）共包含969个测点数据，测点间距介于2000米至4000米之间。该数据集采集区域位于新南威尔士州（New South Wales，简称NSW），于1997年由澳大利亚地质调查组织（Australian Geological Survey Organisation，简称AGSO）与新南威尔士州地质调查局（Geological Survey of New South Wales，简称GSNSW）依托项目编号199705完成采集工作。
