Tasmanian Detailed Gravity (P198752), 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 (P198752) contains a total of 357 point data values acquired at a spacing of 100 metres. The data is located in TAS and were acquired in 1987, under project No. 198752 for None.

重力数据用于测量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流程开展处理，以确保记录得到的重力响应仅源于地下岩石的影响。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。经处理的数据会由GA地球物理学家进行质量核验，以保障GA发布的最终数据符合使用要求。本次发布的塔斯马尼亚精细化重力数据集（P198752）共计包含357个测点数据，测点间距为100米。该数据集的布设区域为塔斯马尼亚州（TAS），采集于1987年，所属项目编号为198752，委托方为无。
