摘　　要：研究了营房 -牛圈矿床成矿物质基础、来源 ,分析构造控矿特征 ;认为深大断裂控制岩浆成矿带 ,线环交织构造控制热流体 ,剪切带控制矿体空间位置 ;提出银矿床属深源热流体隐爆 -交代型矿床。Based on the studies of ore source of Yingfang-Niujuan silver deposit, the ore-control characters, such as deep seat ed fault control on magmatic mineral zone, line-circle anastomosing structure c ontrol on hydrothermal fluid, shear belt control on ore distribution, are analys ed. The ore-genesis belonging to deep resource hydrothermal fluid cryptoexplosi on metasomatism was put forward.
