摘　　要：北淮阳构造东段多金属矿床的成因上多与岩浆的隐爆作用有关,沙坪沟特大斑岩型钼矿的形成与岩浆的隐爆作用也有着密切关系,岩浆多期次的隐爆为矿质的运移、富集成矿提供了动力来源和容矿空间。本文从构造、岩浆岩、矿体等基本特征入手,从时间上、空间上、成矿过程上探讨矿床的隐爆特征,分析沙坪沟钼矿成矿过程:隐伏斑岩岩浆侵位(多期次)—隐爆(多期次)—含矿流体活动—成矿。Geological exploration work has ended for the Shapinggou molybdenum ore deposit, Jinzhai County, Anhui Province, providing a proven Mo metal reserve of 2.45 million tons. Starting with basic features of structure, magmatic rock and ore body, and in view of time, space and mineralization process, this paper discussed cryptoexplosion aspect of the deposit and concluded the mineralization process as： super and hidden porphyry magma emplacement （multi-stage）-cryptoexplosion （multi-stage）-ore-bearing fluid activity-mineralization.
