Southeast Tasmania Detailed Gravity Survey, Cygnet (P196560), 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 Southeast Tasmania Detailed Gravity Survey, Cygnet (P196560) contains a total of 163 point data values acquired at a spacing between 400 and 800 metres. The data is located in TAS and were acquired in 1965, under project No. 196560 for Mineral Resources Tasmania (MRT).

重力数据可用于测量因地球表层下方岩石密度变化而产生的微小重力变化。所采集的数据将通过标准方法进行处理，以确保所记录的响应仅由地下岩石引起。由此得到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地球物理学家开展质量核验，以确保GA发布的最终数据满足使用需求。本次塔斯马尼亚州东南部赛格尼特（Cygnet）详细重力调查（项目编号P196560）共收录163组测点数据，测点间距介于400米至800米之间。本次数据的采集区域位于塔斯马尼亚州（TAS），采集工作于1965年开展，隶属于塔斯马尼亚矿产资源局（Mineral Resources Tasmania, MRT）编号为196560的项目。
