Tasmanian Gravity Data (P198849), 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 Gravity Data (P198849) contains a total of 92 point data values acquired at a spacing between 20 and 100 metres. The data is located in TAS and were acquired in 1988, under project No. 198849 for None.

重力数据用于测量地球表层下方岩石密度变化所引发的微小重力变化。所采集的原始数据将通过标准流程进行处理，以确保记录得到的响应仅源自地下岩石的影响。经处理后得到的数据集可通过解译揭示地下地质构造。处理后的数据将由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。本次的塔斯马尼亚重力数据集（P198849）共包含92个测点数据，测点间距介于20米至100米之间。该数据集的采集区域位于塔斯马尼亚州（TAS），采集工作于1988年开展，隶属于编号为198849的项目，无特定委托方。
