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.
