| 摘 要： | 东秦岭大别山段矿化中酸性小岩体集中分布在秦岭钼（钨）成矿带东段,是我国重要的钼（钨）矿带之一。矿化中酸性小岩体多是受北北西向和北北东向断裂构造控制的复式杂岩体。形成环境从浅成—超浅成—深成相,Mo元素丰度由高—低,分为浅成—超浅成斑岩钼（铜）矿化、中—深成斑岩—矽卡岩型钼（钨、铜）矿化和浅成斑岩型钼矿化三种类型。小岩体主导的钼（铜）矿床具有明显的金属（元素）或矿物组份分带,表现为各带间金属元素含量递变及不同矿物组合按序析出,成矿物质主要来源于下地壳。

| Abstract: | The Dabie Mountains region is lies in the eastern section of the Qinling Mo(W) mineralization belt.The Mineralized intermediate and acid composite minor intrusions are controlled by NNW-and NNE-trending faulted structures.Mo content decreases with the depth of the intrusion emplacement.The mineralization may be divided intro porphyry Mo-(Cu) one related to hypabyssal intrusions,porphyry-skarn Mo-(W-Cu) one related to plutonic intrusions and porphyry Mo one related to hypabyssal intrusions.The mineralization... |
