Mount Isa Detailed Gravity (P199341), 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 Mount Isa Detailed Gravity (P199341) contains a total of 3165 point data values acquired at a spacing between 500 and 1500 metres. The data is located in QLD and were acquired in 1993, under project No. 199341 for Department of Resource Industries (Queensland).

重力数据用于监测地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据将通过标准化处理流程进行加工，以确保记录得到的响应仅由地下岩石引起。经处理后生成的数据集可通过解译，用以揭示地下地质构造特征。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需求。本次发布的芒特艾萨精细化重力数据集（P199341）共计包含3165个测点数据，测点间距介于500米至1500米之间。该数据集的采集区域位于昆士兰州（QLD），是1993年为昆士兰州资源产业部编号为199341的项目所获取的成果。
