论述了德兴式斑岩型矿床的构造－岩浆－成矿体系．德兴铜矿田是比较典型又独具特色的斑岩型Ｃｕ（Ｍｏ，Ａｕ）矿床．银山Ｃｕ，Ａｕ，Ｐｂ，Ｚｎ，Ａｇ多金属矿区是比较典型的火山－次火山－斑岩成矿体系．三级断裂（裂隙）系统在不同尺度上控岩控矿．中酸性岩浆活动提供成矿金属元素、成矿热流体、成矿热驱动力和成矿空间，并促使围岩“矿源层”中的成矿物质活化转移参与成矿．德兴式斑岩型矿床是构造作用－岩浆作用－成矿作用三位一体统一的地质作用的产物 The tectonic-magmatic-ore-forming system of Dexing porphyry deposit is discussed. Dexing copper ore field is a typical and unique porphyry Cu (Mo, Au) deposit. The Yinshan Cu, Au, Pb, Zn and Ag polymetallic deposits are typical volcanic-subvolcanic-porphyry metallogenic systems. Three-stage fracture (fracture) system controlled rock control at different scales. Meso-acid magmatism provides metallogenic elements, metallogenic hydrothermal fluids, metallogenic thermal driving forces and metallogenic space, and promotes the activation and metastasis of metallogenic materials in the “source rock” of the surrounding rock to participate in mineralization. Dexing type porphyry deposit is a product of the tectonic-magmatic-mineralogical and geological interaction
