摘　　要：勉略宁三角区分布大量的韧性剪切带型金矿。小燕子沟金矿按矿化类型可分为石英脉型、构造蚀变岩型、磁铁石英岩型等,主要控矿因素为碧口群地层及韧性剪切带,其中韧性剪切变形对矿体的形成起了主导控制作用。Ductile shear zones are developed well in a trigonum surrounded by Mianxian-Lueyang- Ningqiang counties, in which gold deposits occur. Gold mineralization in Xiaoyanzigou can be clas- sified into quartz-vein type, structural altered rock type and magnet quartzite type, and the major ore-controlled factors are the Bikou group and ductile shear zones, in which ductile shear deformation are dominant in formation of ore bodies.

关 键 词：小燕子沟 金矿 碧口群 韧性剪切变形
