Rockhampton Gravity along BMR Seismic Lines, Line 2 (P198902), 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 Rockhampton Gravity along BMR Seismic Lines, Line 2 (P198902) contains a total of 126 point data values acquired at a spacing between 100 and 500 metres. The data is located in QLD and were acquired in 1989, under project No. 198902 for Bureau of Mineral Resources (BMR).

重力数据可用于监测地球表层下方岩石密度变化引发的微小重力场扰动。所采集的原始数据将通过标准处理流程进行校正与加工，以确保记录的重力响应仅由地下岩石的密度变化所引起。经处理得到的数据集可通过解译，揭示地下地质构造的特征。经处理后的数据集会由澳大利亚地质调查局（Geoscience Australia，简称GA）的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。本次的罗克汉普顿地区沿BMR地震测线2号（P198902）重力数据集总计包含126组测点数据，测点间距介于100米至500米之间。该数据集采集于昆士兰州（Queensland，简称QLD），由矿产资源局（Bureau of Mineral Resources，简称BMR）于1989年在编号为198902的项目框架下完成采集。
