Tasmanian Gravity Data (P199050), 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 (P199050) contains a total of 337 point data values acquired at a spacing between 200 and 1000 metres. The data is located in TAS and were acquired in 1990, under project No. 199050 for None.重力数据用于监测地球表面下方岩石密度变化所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，以确保记录的响应仅由地下岩石的密度变化引起。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地球物理学家进行质量核验，以保障GA发布的最终数据满足使用需求。本塔斯马尼亚重力数据集（P199050）共计包含337组测点数据，测点间距介于200米至1000米之间。该数据集布设区域位于塔斯马尼亚州（TAS），采集工作完成于1990年，对应项目编号为199050，委托方信息未标注。
