| 摘 要： | 沙拉哈达钨矿区处于内蒙地轴北缘和大兴安岭地槽褶皱系的交接处.矿化主要分布在安山玢岩内,矿体主要由含矿石英脉组成,矿脉中普遍含黑钨矿、白钨矿、黄铁矿及多金属硫化物.与钨矿有关的侵人岩体主要是燕山期黑云母花岗岩及花岗斑岩.围岩蚀变以硅化、云英岩化、绢云母化为主.该矿床属高温热液成因类型.

| Abstract: | The Shalahada ore field is located in the junction of the north rim of Inner Mongolian axis and the Daxinganling geosynclinal folded system. The mineralization is distributed in mainly andesite porphyrite, with orebodies composed of quartz veins containing wolframite, scheelite, pyrite and polymetallic sulfide. The intrusive rocks related to the wolfram are Yanshanian biotite granite and granite porphyry. The wallrock alterations mainly include silicification, greisenization and sericitization. The genesis of the deposit belongs to hypothermal type. |
