Queensland Gravity Data (P199345), 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 Queensland Gravity Data (P199345) contains a total of 187 point data values acquired at a spacing between 500 and 5000 metres. The data is located in QLD and were acquired in 1993, under project No. 199345 for None.

重力数据用于测量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，以确保记录的重力响应仅由地下岩石引起。经处理后得到的数据集可通过解译揭示地下地质构造。GA地球物理学家会对处理后的数据开展质量核查，以确保GA发布的最终数据符合使用要求。本次发布的昆士兰州重力数据集（P199345）共包含187个测点数据，测点间距介于500米至5000米之间。该数据集的采集区域位于昆士兰州（QLD），于1993年依托编号199345的项目完成采集，委托方标注为None。
