Wyndham-Daly Waters-Nutwood Downs Gravity (P196007), 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 Wyndham-Daly Waters-Nutwood Downs Gravity (P196007) contains a total of 323 point data values acquired at a spacing between 5000 and 8000 metres. The data is located in NT, WA and were acquired in 1960, under project No. 196007 for Bureau of Mineral Resources (BMR).

重力数据用于测量因地球表层下方岩石密度变化所引发的微小重力变动。所采集的数据均通过标准流程开展处理，以确保记录得到的响应仅由地下岩石所引发。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地球物理学家进行质量核查，以确保GA发布的最终数据符合使用要求。本温德姆-戴利沃特斯-纳特伍德当斯重力数据集（P196007）共计包含323组测点数据，测点间距介于5000米至8000米之间。该数据采集于北领地（Northern Territory, NT）与西澳大利亚州（Western Australia, WA）境内，由矿产资源局（Bureau of Mineral Resources, BMR）以项目编号196007于1960年组织采集。
