Paleovolcanism and mineralization in the mianluening area, southern Shaanxi

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.
