摘　　要：通过对勉略宁矿集区新元古代火山岩与古火山机构的系统识别、解析与恢复,对火山作用旋回与韵律特征、火山作用时空特征的系统研究,阐明了古火山机构与铜铅锌多金属矿的时空耦合关系及成因联系,深化了对碧口岩群火山岩成矿作用与成矿规律的认识,为实现找矿突破提供了理论依据和找矿方向。Through systematic identification,analysis,and restoration of Neoproterozoic volcanic rocks and paleovolcanic structures in the Mianluoning ore concentration area,this paper thoroughly examines the characteristics of volcanic cycles and rhythms and the spatial and temporal aspects of volcanism.It explores the space-time correlation and genetic relationship between ancient volcanic processes and Cu-Pb-Zn polymetallic deposits,thereby enhancing the understanding of the metallogenic processes and regularities of volcanic rocks within the Bikou rock group.This work provides a theoretical foundation for breakthroughs in ore prospecting,guiding future exploration.
