西藏班公湖—怒江成矿带燕山成矿阶段矿床成矿系列研究进展和存在的问题

Research Progress and Existing Problems of Metallogenic Series of Ore Deposits Yanshan Metallogenic Belt in the Bangongco-Nujiang Metallogenic Belt

西藏班公湖—怒江成矿带具有较好的找矿前景,现已探明Cu、Fe等金属类矿床(点)近600处。区内成矿类型多样,早期发现有岩浆型铬铁矿,此后随着勘探的深入,进一步探明了浅成低温热液型铜(金)矿、斑岩型铜(金)矿、矽卡岩型铁(铜)矿、热液-蚀变岩型金矿、热液型钨矿。前人对于西藏班公湖—怒江成矿带的研究主要集中在中段及西段,东段工作程度较低。因此主要针对西藏班公湖—怒江成矿带中段及西段的燕山期典型矿床进行浅述,以期归纳出现阶段班公湖—怒江成矿带燕山成矿阶段矿床成矿系列的研究进展,并进一步探讨其存在的相关问题。

Bangongco-Nujiang Metallogenic Belt has excellent geological conditions and potential for mineralization, there has found more than 600 Cu, Fe, Cr, Pb-Zn deposits, except for the earlier discovery of magmatic chromite it＇s also include： epithermal copper（ gold） deposits, porphyry copper （ gold） deposits, skarn iron （ copper） mine, hydrothermal-altered rock type gold deposit, epithermal tungsten ore and some lead-zinc mine included. Previous research of Bangongco-Nujiang Metallogenic Belt is mainly concentrated in the middle and western, while the eastern is still in lower research. Therefore, this passage focused on the typical ore deposits Yanshan metallogenic belt metallogenic stages in the middle and western of Bangongco-Nujiang metallogenic Belt for the summary of research progress and existing problems of metallogenic series of ore deposits Yanshan metallogenic belt in Bangongco-Nujiang metallogenic belt.
