凡口铅锌矿矿体空间产出规律及控矿因素分析

摘要

凡口铅锌矿处于南岭锡多金属成矿带中段核心区南侧，矿区构造发育，岩浆活动不强，是中国最为典型的“一富、二大、三集中、四隐伏”的超大型铅锌矿床。从矿体的形态和产状、矿石矿物成分与矿物组合、赋矿地层、围岩蚀变等方面论述凡口铅锌矿的矿体地质特征及矿体空间产出规律，并分析其控矿因素，研究表明，本矿体形成受断裂构造、地层、沉积相三者控制。%Fankou lead-zinc deposit,located in middle part of the Nanling tin polymetallic metallogenic belt,is a typical“high-grade,large tonnage,unexposed” suppergiant lead-zinc deposit in China.From the shape and the occurrence of ore body,ore mineral composition and mineral assemblage,ore-bearing strata,wall rock alteration,the paper discusses the ge-ological characteristics of orebody,focuses on the occurence law of orebody and the ore-controlling factors.
