Tasmanian Gravity Data (P199552), 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 (P199552) contains a total of 415 point data values acquired at a spacing between 3000 and 5000 metres. The data is located in TAS and were acquired in 1995, under project No. 199552 for Mineral Resources Tasmania (MRT).

重力数据用于表征地球表层下方岩石密度变化引发的微小重力场变化。所采集的原始数据将通过标准化处理流程进行加工，以确保所记录的重力响应仅由地下岩石的密度变化引发。经处理得到的数据集可通过地质解译揭示地下地质构造特征。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发布的最终数据满足应用需求。本次发布的塔斯马尼亚重力数据集（P199552）共计包含415组测点数据，测点间距介于3000米至5000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1995年完成，隶属于塔斯马尼亚州矿产资源部（Mineral Resources Tasmania, MRT）编号为199552的项目。
