| 摘 要： | 西成铅锌矿化集中区已发现多处中小型金矿床(点),主要矿化类型有微细浸染型和石英脉型,代表性矿床有安家岔金矿床和小沟里金矿床。综合研究表明,中泥盆统安家岔组和西汉水组是主要矿源层,岩浆活动为成矿提供热动力条件和部分成矿物质,层间破碎带及构造交汇部位矿化富集。"攻深找盲"是今后勘查的主攻方向,同时,应注意在铅锌矿床外围有利的构造部位及有岩浆或深源热液活动的部位找矿。

| Abstract: | Many middle-small gold deposits were found in Xicheng lead and zinc mineralization field and their major types are micro-disseminated type and quartz vein type, whose representative deposits are Anjiacha deposit and Xiaogouli deposit. Anjiacha gronp and Xihanshui group in Middle Devonian system are the main mineral source bed. Magma activities provided the thermodynamic conditions and part of ore-forming substance. The ore-forming minerals enriched in the interlaminar broken belt and structure convergence position. The major prospecting work in the future is to find in depth and blind orebodies. At the same time, the prospecting work should pay attention to the places of advantaged structures and magma or hot liquid activity parts. |
