湖北省麻城市白鸭山钼矿床是大别山南麓新发现的斑岩型钼矿床，产于早白垩纪白鸭山花岗岩体内部，白鸭山钼矿床4件辉钼矿铼锇同位素模式年龄为（109．3±0．6）Ma～（110．0±1．0）Ma，等时线年龄为（110．7±2．8） Ma，代表了流体成矿年龄，根据白鸭山所测同位素年龄数据，结合野外接触关系，确定为早白垩世晚期。白鸭山岩体存在多期次岩浆侵入活动，白鸭山钼矿与（110．7±2．8） Ma岩浆活动有关，结合区域成矿地质背景，推测在早白垩纪晚期，白鸭山钼矿床可能是板块碰撞造成岩浆作用及相关流体活动的产物。

Baiyashan Mo deposit is a porphyry molybdenum deposit newly discovered in Macheng City in Hubei Prov -ince,internally generated by the previous view that the early Cretaceous Baiyashan granitic pluton ,age of Re-Os isotope pattern Baiyashan molybdenum deposit 4 pieces of molybdenite was (109.3 ±0.6) Ma to (110 ±1.0) Ma,isochron age (110.7 ±2.8) Ma,on behalf of the fluid ore forming age ,with Baiyashan measured data of isotopic age data ,according to the relation of contact in the field ,the late Early Cretaceous judgment ,Baiyashan rock has multiperiodic magmatic ac-tivities,combined with regional geological background ,presumably in the early Late Cretaceous period ,Baiyashan molyb-denum deposit may be a product of the Yang Zi plate and the North China plate collision orogenic stage structure —mag-matism and related fluid activity .
