摘　　要：克其克阿孜北玉石矿位于和田玉成矿带西段,赋存于下元古界欧阳麦切特群,矿体呈透镜状产出,受岩体、地层、断裂构造多重因素控制,矿石自然类型为透闪石岩型,为三级品透闪石质青玉。其成因类型属中低温热液交代型透闪石类软玉矿床。通过对该矿成矿地质特征和找矿标志的总结,为该区今后的玉石找矿工作提供了思路。Keqike'azi North jade deposit is located in the western section of Hetian jade metallogenic belt,and occurs in the Lower Proterozoic Ouyang Maichete Group.The ore body is lenticular,and the natural type of the ore is tremolite type,which is a third-grade tremolite sapphire.Hydrothermal contact metasomatism is the main mineralization of jade,and its genetic type belongs to tremolite nephrite deposit with medium-low temperature hydrothermal metasomatism.By summarizing the metallogenic geological characteristics and prospecting indicators of this mine,it provides ideas for jade prospecting in this area in the future.
