摘要
辽东青城子地区是我国重要的有色和贵金属成矿区。在分析其成矿地质条件、地球化学和地球物理特征、遥感影像特征的基础上,建立了综合信息找矿模型,提出了有利的含矿层位、各级断裂构造及中生代岩体对金银多金属矿化起着重要的控制作用。在找矿模型的指导下,该地区主要通过详细地质调查、水系沉积物测量、高精度磁测扫面、遥感解译等工作,寻找与矿化有关的异常信息,进一步筛选出10余处可供调查评价并且资源潜力巨大的找矿远景区。
The Qingchengzi area in Liaoning Province is the most important metallogenic region of non-ferrous and noble metals in China. A synthetic information model of searching for the deposits was set up bythe present authors based on analyses of the deposits in geology,geochemistry, geophysics and remote sensing. It is suggested that the stratigraphic horizon, intrusion and faults of different orders played a very important role in gold, silver and polymetal ore-forming processes. Under guidance of the prospecting model and through geological survey, stream sediment measurement, high-precision magnetic measurement, remote sensing interpretation, a voluminous of information of mineralization were collected and more than ten perspective sites are selected and investigated. The Qingchengzi metallogenic region has been proven to be of high potential.
