| 摘 要： | 北票二道沟地区流纹质火山岩喷溢发生于167.5-135.36Ma,其西侧又相继有金厂沟梁南花岗岩(127.9Ma)和对面沟斑状花岗闪长岩株(126.3-121.5Ma)侵位。金厂沟梁、二道沟、长皋沟三个金矿床均产于岩株主动侵位在周边形成的放射状裂隙中。区内EW向断裂和NW向断裂复合控制火山岩、花岗岩,NW向鸡冠山断裂是主要岩浆通道,并控制金矿化。

| Abstract: | The rhyolitic volcanic rocks erupted during 167-135Ma in Erdaogou area,Beipiao County,and emplacement of the South Jinchanggouliang granitic stock and Duimiangou porphyritic granodioritic stock took place during 128Ma and 126-121Ma to the two sides of the area.The Jinchanggouliang,Erdaogou and Changgaogou gold deposits occurred in the radial fractures produced by the emplacement of the stocks.It is suggested that volcanic rock and granite are controlled by compounding of the EW-trending faults and the NW-trending faults,and the NW-trending Jiguanshan fault serves as the major channel-way for magmatic intrusion and gold mineralization. |
