摘　　要：夹皮沟新北西带位于太古宙中朝古陆板块与元古宙蒙古海板块之间缝合线上的夹皮沟主剪切带北东盘,是夹皮沟主剪切带的北部边界。新北西带长20余公里,宽几十至百余米,由压扭性碎裂岩及糜棱岩组成。带中产有大型金矿床,老牛沟段是今后新北西带中及上下盘找矿的主要目标,是夹皮沟矿区又一处重要的找矿远景区。The new westnorthern part of Jiapigou lies in the eastnorthern plate of the main shear zone of the suture line between the Archean Sino-Korean ancient land plate and the Proterozoic Mongolia sea plate,which is the north boundary of Jiapigou main shear zone.The new westnorthern part is more than 20 km in length,tens-more than one hundred m in width,which is composed of compresso-shear structural cataclastic rock and mylonite.There are large gold deposits in the study area,so,the Laoniugou area should be a ma...
