南秦岭大岔沟一带钨多金属矿地质特征及找矿潜力分析

Geological characteristics and prospecting potential of tungsten polymetallic deposits in Dachagou area,South Qinling

大岔沟钨多金属矿位于镇安西部钨矿集中区,周边已发现东阳钨矿、棋盘沟钨、核桃坪钨矿、新铺钼矿等。本次调查在大岔沟和画皮沟一带发现了WⅠ、WⅡ 两条钨矿带,矿体主要赋存于印支期石英二长岩外接触带大理岩中,受北西西向、北东向断裂控制,属于断控矽卡岩型矿床。综合研究表明,南秦岭大岔沟一带具有寻找钨多金属的巨大潜力。

Dachagou tungsten polymetallic mine is located in the tungsten concentration area in the west of Zhen’an.Dongyang tungsten mine,Qipangou tungsten mine,Hetaoping tungsten mine and Xinpu molybdenum mine have been found around it.In this survey,two tungsten ore belts named WⅠ and WⅡ were found in Dachagou and huapigou.The ore body mainly occurs in the marble in the outer contact zone of Indosinian quartz monzonite,which is controlled by NWW and NE faults and belongs to fault controlled skarn deposit.The comprehensive study shows that Dachagou area of South Qinling Mountains has great potential to find tungsten polymetallic.
