摘　　要：卡拉先格尔铜矿位于阿尔泰成矿带南缘东段,通过对阿尔泰南缘卡拉先格尔铜矿发育的构造变形的分析,认为矿区内发育的脆韧性剪切带对矿化、围岩蚀变的形成和空间展布具有一定的控制作用。今后在矿区内找矿不仅要重视岩性对矿化的控制,还要重视韧性剪切变形带对矿化的制约,尤其是位于剪切带的斑岩岩体与围岩的接触带附近,岩体微裂隙发育,易形成矿体的富集。The Kalaxianggeer Halasu copper deposit is situated in the eastern segment of the southern margin of the Ahay metallogenic belt. Analysis of the structural deformation in the copper deposit shows that the brittle-ductile shear zone in the copper area has a certain controlling effect on mineralization and country rock alteration and their distribution. In the future copper exploration in the area, attention should be paid not only to the controls of the lithology on mineralization but also to the constraints of the ductile shear zone on the mineralization. In particular, importance should be attached to the contact zone between porphyries and country rocks in the shear zone, where well developed microfractures favored the concentration of orebodies.
