摘　　要：吉拉铜金矿位于冈底斯成矿带中段南缘,谢通门铜金富铁矿集区,与著名的雄村特大型铜金矿毗邻,成矿条件优越,化探异常显示Cu、Au、Pb、Zn、Ag元素标准差、变化系数大,富集能力强,元素套叠好,异常浓集中心突出,浓集中心与矿化(体)相对应,属典型的致矿异常,矿(化)体分布与大理岩和闪长岩接触带上。建议应以冈底斯成矿带铜多金属矿成矿找矿模式及雄村矿床的发现经验来指导找矿,继续加强勘查和研究工作,将有望实现斑岩型、矽卡岩型铜多金属矿,韧性剪切带型、蚀变岩性金铜矿的重大找矿突破。Jila copper-gold deposit has an excellent metallogenic background,which closes to Xiongcun large copper-gold deposit and locates in the Xietongmen copper-gold rich iron ore concentration area of southern margin of the middle Gangdese.Geochemical anomalies showed that element anomalies of Cu,Au,Pb,Zn,Ag belong anomalies related to mineralization.Orebody distributes in the contact zone between marble and diorite.It is suggested that under the guide of metallogenic regularity of copper-polymetallic ore belt of gangdese and successful exploration experience of Xiongcun copper-gold deposite and Continue to strengthen geological exploration and research work.Jila copper-gold deposite expected to achieve geological exploration breakthrough of porphyry-type and skarn-type copper polymetallic deposit and ductile shear zone-type and altered rock-type gold deposite.Ore-prospecting potential of Jila is tremendous.
