摘　　要：河南省嵩县钾长石英脉型钼矿呈似层状与熊耳群整合产出,倾角较缓,一般15°左右,矿层1～12层不等,一般2～5层,矿脉多有隐伏,在熊耳群分布区内多处发现了同类型的钼矿床。经对矿床稀土元素和氢氧同位素测试分析,认为矿脉为火山期后热液沿火山岩层间裂隙充填成矿,具有层控矿床的特点。因而,结合该类矿床的特点,通过对已经找到的矿床的分布面积、控制深度及控制的资历源量研究,对该区域作出成矿预测。The potassium feldspar quartz vein - type molybdenum deposits in Songxian county of Henan province, are stratiform - like and have a conformable contact with the rocks of Xiong＇er group. Dip of ore layers is usually small and about 15°. The number of ore layers ranges from 1 to 12, mostly 2 to 5. Ore veins are usually concealed. The same kind of molybdenum deposits are discovered in many places where the rocks of Xiong＇er group appear. Through the test and analysis of the rare earth element and hydrogen -oxygen isotope in molybdenum deposits, it is concluded that the hydrothermal fluid of post volcanic stage fills the fissures among the volcanic rock layers and forms deposits. These deposits are eharaetered by strata bound. In combination with the characteristics of this kind of deposits, through the study on the distribution areas, controlled depth and controlled resource amount, metallogenie prognosis assessment of this area has been made.
