摘　　要：在成矿过程中由于控矿构造的级别、规模及序次的不同,导致对成矿的条级系统控制。工业矿体、矿柱或富矿包常产出于特定的构造部位,很显然是有利的构造部位控制了矿化的局部富集。构造对金属内生成矿演化更重要和直接的控制表现在成矿期构造的脉动对成矿多阶段演化方面。根据矿化形成环境,又可以分为碰撞造山期成矿、松弛期(伸展)成矿、走滑拉分盆地成矿和剪切带扩容成矿。通过对我国内生矿床与地质演化、内生矿床构造、成矿机理和成矿作用的分析,初步厘定出内生矿床的成矿模式,并建立了圈定成矿有利区的标志。In the process of mineralization,due to the difference in rank,scale and order of structures orebody,mine colomn or rich ore bag are often produced in the specific structural parts.Obviously,it is controlled by favourite structure.The important and direct control of the structure to metal endogenetic mineralization evolution are representative on the affect of pulse action of structure to the multi-stage of mineralization evolution.According to the formation environment of the mineralization,it can be classified as collision orogeny mineralization,release（extension）mineralization,slide draw-division basin mineralization and shear zone extension mineralization.Throng the discuss of endogenetic deposit in the geological evolution,structure and formation machenism,the metallogenic model was preliminary established,and the criteria for delineating favourable metallogenic area was identified.
