摘　　要：丰宁—承德东西向成矿带是冀北重要的金多金属成矿带,成矿地质条件优越,深部及外围找矿潜力较大。幔枝构造是近二十余年兴起的新的构造理论,尝试运用幔枝构造成矿理论分析了丰承幔枝构造特征及与矿产分布的时空关系,并进一步分析了幔枝构造对金银多金属成矿的控矿作用,旨在为该带进一步找矿提供思路。The Fengning-Chengde east—west metallogenic belt is an important gold polymetallic metallogenic belt in Northern Hebei,with superior metallogenic geological conditions and great prospecting potential in the deep and peripheral areas.Theory of the mantle branch structure has been proposed for more than twenty years.This paper tries to use the theory of mantle branch structure to analyze the characteristics of Fengcheng mantle branch structure and its spatiotemporal relationship with mineral distribution,and further analyzes the mineralization control on gold-silver polymetallic deposits.The purpose of the study is to provide a new idea for ore prospecting in this zone.
