摘要
系统地提出了基于三维建模的隐伏金矿体预测方法。通过收集详细的地质信息,构建了地质参数数据库。利用当前金矿体与所有相关地质信息(包括地层、断层、矿化、矿物密度、地球物理、地球化学等)之间的相关性分析,确定了主要成矿预测因素。主要以Quantec 3D系统的建模手段进行分析,并且结合模糊综合评价和正交分析手段,用于确定各主要控矿因素的影响范围。最后得出矿化地质优势值,确定了金矿带的大致区域。通过工程试验验证了预测技术的可行性,相关的高电流密布区块被直观地显示,可作为未来金矿带勘探策略的指南。
The prediction method of concealed gold ore body based on 3D modeling was systematically put forward.By collecting detailed geological information,the geological parameter database was constructed.Using the correlation analysis between the current gold ore body and all relevant geological information(including strata,faults,mineralization,mineral density,geophysics,geochemistry,etc.),the main metallogenic prediction factors were determined.It was mainly analyzed by means of modeling of Quantec 3D system,and combined with fuzzy comprehensive evaluation and orthogonal analysis to determine the influence range of main ore control factors.Finally,the geological dominant value of mineralization was obtained,and the approximate area of the gold belt was determined.The feasibility of the prediction technology was verified through engineering tests,and the relevant high current densely distributed blocks were directly displayed,which could be used as a guide for future gold belt exploration strategies.
