Buchanan Gravity (P199130), 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 Buchanan Gravity (P199130) contains a total of 410 point data values acquired at a spacing between 1000 and 5000 metres. The data is located in QLD and were acquired in 1991, under project No. 199130 for Bureau of Mineral Resources (BMR); Department of Natural Resources, Mines and Energy (Queensland).

重力数据用于测量地球表层下方岩石密度变化引发的微小重力变动。所采集的数据均通过标准流程处理，以确保记录得到的响应仅源于地下岩石。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。本巴坎重力数据集（Buchanan Gravity，编号P199130）共包含410个测点数据，测点间距介于1000至5000米之间。该数据集采集于昆士兰州（QLD），于1991年完成采集，隶属于矿产资源局（Bureau of Mineral Resources, BMR）及昆士兰州自然资源、矿产与能源部的199130号项目。
