Tasmanian Detailed Gravity (P198451), 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 Tasmanian Detailed Gravity (P198451) contains a total of 833 point data values acquired at a spacing between 50 and 1000 metres. The data is located in TAS and were acquired in 1984, under project No. 198451 for Mineral Resources Tasmania (MRT).

重力数据用于测量地球地表下方岩石密度变化所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，以确保所记录的重力响应仅由地下岩石引起。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。本塔斯马尼亚详细重力数据集（P198451）共计包含833个测点重力数据，测点布设间距介于50米至1000米之间。该数据集采集于塔斯马尼亚州，数据采集工作完成于1984年，由塔斯马尼亚矿产资源局（Mineral Resources Tasmania, MRT）依托项目编号198451实施。
