GIG, Tennant Creek Area, NT (P199280), 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 GIG, Tennant Creek Area, NT (P199280) contains a total of 131 point data values acquired at a spacing between 50 and 2500 metres. The data is located in NT and were acquired in 1992, under project No. 199280 for Giants Reef Mining Pty Ltd.重力数据用于监测地球表层下方岩石密度变化所引发的微小重力场变动。所采集的数据均通过标准化流程开展处理，以确保记录得到的响应仅源自地下岩石。经处理后生成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地球物理学家进行质量核验，以确保GA发布的最终数据符合使用需求。本次GIG数据集（北领地滕南特克里克区域，编号P199280）共包含131个测点数据，测点间距介于50米至2500米之间。该数据集采集于北领地，采集时间为1992年，对应为巨人礁矿业私人有限公司（Giants Reef Mining Pty Ltd）实施的编号199280项目。
