Mt Isa Area E Gravity Survey (P200644), 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 Mt Isa Area E Gravity Survey (P200644) contains a total of 6123 point data values acquired at a spacing of 4000 metres. The data is located in QLD and were acquired in 2007, under project No. 200644 for Department of Natural Resources, Mines and Water (Queensland).

重力数据可捕捉地球表层下方岩石密度变化引发的微小重力场扰动。所采集的数据均通过标准化流程处理，以确保记录的重力响应仅由地下岩石引起。经处理得到的数据集可通过解译揭示地下地质构造。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发布的最终数据符合使用要求。本次芒特艾萨（Mt Isa）E区重力测量项目（编号P200644）共包含6123个测点数据，测点间距为4000米。该数据集采集区域位于昆士兰州（QLD），采集工作于2007年开展，对应昆士兰州自然资源、矿产与水利部编号为200644的项目。
