Hughenden (P199442), 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 Hughenden (P199442) contains a total of 441 point data values acquired at a spacing of 900 metres. The data is located in QLD and were acquired in 1994, under project No. 199442 for Department of Minerals and Energy (Queensland).

重力数据用于表征地球表层下方岩石密度变化引发的微小重力场变动。所采集的数据将通过标准化流程处理，确保记录的响应仅源于地下岩石的影响。经处理得到的数据集可通过解译，用以揭示地下地质构造。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。本次汉登（Hughenden，编号P199442）数据集共包含441个测点数据，测点间距为900米。该数据采集于昆士兰州（QLD），采集时间为1994年，隶属于昆士兰州矿产与能源部199442号项目。
