摘要
论述了中国东部中生代火山岩型金银矿床的成矿地质背景及控矿条件,包括基底地层、火山建造、次火山岩及构造与矿化的关系.将该类型矿床分为3个成因类型,并综合论述了几类矿床的赋矿围岩、容矿构造、矿体形态、矿石建造、矿化分带及蚀变等主要地质特征.
The metallogenic geological setting and ore-controlling condition of the Mesozoic volcanic rocks hosted Au-Ag deposits in the eastern China, including the relation of mineralization to basement,volcanic formation, sub-volcanic rock and structure are discussed. These deposifs are classitied into three genetic types, and the main geological characteristics including host rock, ore -bearing structure,shape of ore body, ore formation, ore zoning and alteration are reviewed.
