摘　　要：烈马咀钼矿位于武当—桐柏—大别成矿带东段南缘。围岩为早白垩世细粒含斑黑云二长花岗岩,围岩蚀变从外向内分带明显,可划分为绢英岩化带、黄铁矿化带、绿泥石化带、钾化硅化带,地表条带状钼矿体产出于钾化硅化带,围岩蚀变与钼矿化具典型斑岩钼矿特征,反映矿区深部可能存在斑岩型钼矿床。Liemazui porphyry molybdenum deposit is found in anomaly verification,which is located in eastern of Wu- dang-Tongbai-Dabie metallogenie belt. The country rock is mainly consist of porphyriticbiotite monzonitic granite in Early Cretaceous Epoch,and the country rock aheration can be divided into several zones from outside to inside such as Gs zones,Py zones,Chl zones and Kp-Si zones. Molybdenum ores in the surface is mainly occurred in the Kp-Si zones with strips. The relationship between country rock alteration and mineralization reflects that there may have porphyry molybde- num deposit in the deep of this area.
