摘　　要：总结了河南省钼矿成矿类型,运用斑岩型钼矿成矿模型,以东沟钼矿和纸房钼矿2个矿床为实例,探索就矿找矿新模式。斑岩型钼矿是秦岭—大别山地区钼矿成矿主要类型,是由于深部的岩浆热液上升入侵,打通了上升通道,使得成矿流体能够通过通道运移,在合适部位沉积、聚集成矿,成矿机理属于热液成矿理论。根据热液成矿理论,建立了斑岩型钼矿成矿模型。研究了斑岩型钼矿成矿时代、控矿因素、岩矿特征、矿体位置等,并在东沟钼矿和纸房钼矿2个矿床中进行了验证。讨论了2个矿床控矿要素,预测了矿床的深部和周边可能存在矿体的位置及矿种的可能性,为斑岩型矿床就矿找矿提供了地质依据。In order to carry out the new round of breakthrough strategic actions for mineral exploration in Henan province and innovate mineral exploration models,The types of molybdenum mineralization in Henan province was summarized,and used the porphyry molybdenum mineralization model to explore new mineral exploration models based on Donggou and Zhifang molybdenum deposits as examples.Porphyry type molybdenum deposits are the main type of molybdenum mineralization in Qinling Dabie mountains region.They are formed by the upward intrusion of deep-seated magmatic hydrothermal fluids,which open up upward channels and allow ore-forming fluids to migrate through these channels,depositing and accumulating in suitable locations for mineralization.The mineralization mechanism belongs to the theory of hydrothermal mineralization.This paper establishes a porphyry molybdenum mineralization model based on the theory of hydrothermal mineralization.The mineralization age,ore controlling factors,rock and mineral characteristics,and ore body location of porphyry molybdenum deposits was studied,and verified in the two deposits,Donggou molybdenum deposit and Zhifang molybdenum deposit.Two deposits controlling factors were discussed,and the possible locations and types of ore bodies in the deep and surrounding areas of the deposit were predicted,which providing geological basis for the exploration of porphyry deposits.
