Isa Georgetown (P200140), 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 Isa Georgetown (P200140) contains a total of 5236 point data values acquired at a spacing of 4000 metres. The data is located in QLD and were acquired in 2001, under project No. 200140 for Department of Minerals and Energy (Queensland).

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处理流程进行加工，以确保记录的响应仅源自地下岩石的影响。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查，以确保GA发布的最终数据满足实际应用需求。本数据集为艾萨乔治敦（P200140），共包含5236个测点数据，测点间距为4000米。该数据集采集于2001年，位于昆士兰州（QLD），隶属于昆士兰州矿产与能源部编号为200140的项目。
