摘　　要：东秦岭大别山段矿化中酸性小岩体集中分布在东秦岭钼(钨、铜)矿带东段,呈带状沿深大断裂两侧分布,受构造控制明显。已发现主要钼矿床属斑岩型,成因多与中生代中酸性花岗质斑岩有关。根据斑岩型钼(钨、铜)矿床地质特征,通过控岩控矿构造、围岩蚀变、矿体特征、矿石物质组份及其成矿机制等方面的研究,把东秦岭大别山段斑岩钼(钨、铜)矿划分为浅成-超浅成斑岩钼(铜)矿床,中-深成斑岩-夕卡岩钼(钨、铜)矿床两种类型。Mineralized small intermediate - acidic rock bodies in the Dabieshan of eastern Qinling are mainly distributed in the east sector of eastern Qinling molybdenum （tungsten, copper） ore belt. The rock bodies occur along the two sides of the deep and major faults, and are controlled mainly by structures. Founded molybdenum deposits mainly belong to porphyry type, and are related to Mesozoic intermediate - acid granitic porphyry. Based on geological characteristics of the porphyry molybdenum （ tungsten, copper） deposits, and according to rock - controlling and ore - controlling structures, wall - rock alteration, orebody features, ore components and metallogenic mechanism, porphyry molybdenum （tungsten, copper） deposits in the Dabieshan of eastern Qinling can be divided into hypabyssal - ultrahypabyssal porphyry molybdenum （copper） deposits and intermediate - hypogene porphyry - skam molybdenum （ tungsten, copper） deposits.
