通过对岗讲矿区100多个钻孔资料的对比研究，三维模拟和区域矿床(点)对比分析，提出了岗讲铜钼矿床的成矿模型为，四周以“井字型”断裂环绕，平面以“似环状”形态分布，核部主体为不含矿英云闪长玢岩，并以30°~50°夹角从“柱状”体向四周以岩枝形态侵入，上部呈“蘑菇状”覆盖含矿二长花岗斑岩，在英云闪长玢岩与二长花岗斑岩接触带常伴随强烈的断裂破碎和泥化现象，二长花岗斑岩体内常形成一定规模的斑岩铜钼矿体。根据其成矿模型，寻找闪长玢岩(或者英云闪长玢岩)与二长花岗斑岩接触带及断裂构造交汇部位是今后找矿勘查工作的关键所在。

According to comparison study of data of over 100 drilling holes in Gangjiang mining area as well as three-dimensional simulation and comparison analysis of deposits (mineral occurrence)in this area,this pa-per proposes that metallogenic model of Gangjiang Cu-Mo deposit is a “ring-like”distribution in the plane and is surrounded by “#”shaped faults.The main body of the core is barren palaeophyre which is intruding into the periphery as apophysal injection in columnar form with included angle of 30~50 degree.The upper part is covered by “mushroom-shaped”ore-bearing monzonitic granite porphyry.The contact zone between palaeophyre and monzonitic granite porphyry has intense fracture and argillation.In general,a certain scale of porphyry copper molybdenum ore body may be formed inside the rock body of monzonitic granite porphy-ry.According to its metallogenic model,the contact zone between dioritic porphyrite (palaeophyre)and monzonitic granite porphyry as well as the intersection of faulted structures is the key targets in the future’s prospecting works.
