摘要:
甲玛铜多金属矿床位于冈底斯成矿带内，通过对该矿区内斑岩体出露、剥蚀程度及成矿深度等方面的分析，并与驱龙铜矿床进行对比，对该矿床成矿潜力及找矿方向进行了探讨。综合分析认为，甲玛铜多金属矿区剥蚀程度相对较低，已知斑岩型矿体深部有较大的成矿潜力；结合矿区近年勘查成果，已知层状矽卡岩型矿体深部具有寻找多层矽卡岩型矿体的潜力。已知斑岩型矿体深部、矿区周边出露或隐伏斑岩体是寻找斑岩型矿体的重点找矿方向；已知层状矽卡岩型铜钼矿体深部、矿区西南部的侏罗系叶巴岩组凝灰岩地层是寻找矽卡岩型矿体的重点找矿方向。

Abstract:
Jiama Copper Polymetallic Deposit is located in the Gangdisi metallogenic belt.By analyzing the exposing and denudation degree and metallogenic depth of porphyry body in this area,and comparing with the Qulong Copper Deposit,the metallogenic potential and prospecting direction in this deposit are discussed.The comprehensive analysis shows that the denudation degree is relatively low in Jiama Copper Polymetallic District and the known deep porphyry ore body has great metallogenic potential.Based on recent years’ exploration results,there is potential to seek multilayer skarn type ore bodies deep in known stratiform skarn type ore bodies.The deep part of the known porphyry ore body and the exposed or concealed porphyry body around the district are the key prospecting directions for porphyry type ore bodies.The deep part of the known stratiform skarn type copper-molybdenum ore body and the tuff strata of Jurassic Yeba rock formation in the southwestern part of the district are the key prospecting directions for skarn ore bodies.
