Eumundi Gravity Data (P199140), 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 Eumundi Gravity Data (P199140) contains a total of 259 point data values acquired at a spacing between 250 and 2500 metres. The data is located in QLD and were acquired in 1991, under project No. 199140 for None.

重力数据用于测量因地球表层下方岩石密度变化所引发的微小重力变化。所采集的数据将通过标准流程处理，以确保记录得到的响应仅源于地下岩石的影响。经处理所得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查，以确保GA发布的最终数据符合使用要求。本次的尤蒙迪重力数据集（Eumundi Gravity Data，P199140）共包含259个测点数据，测点间距介于250米至2500米之间。该数据集采集区域位于昆士兰州（QLD），于1991年通过编号为199140的项目完成采集，委托方为无。
