| 摘 要： | 讨论了中秦岭正河金矿床的成矿地质特征，结合成矿流体物理化学条件，重点分析了其构造控矿作用，并对成矿作用进行了探讨。提出山阳-凤镇深大断裂是矿床的导矿构造，蚀变矿化带受控于次级背斜构造，为背斜核部的轴面劈理化带。硫源具幔源与壳源混合的特征，其成矿作用经历了热水沉积-变质变形-构造热液叠加的构造演化过程。

| Abstract: | According to analysis on ore-controlling characteristics of structures, sources of metallogenic material and gold mineralization, Authers think that mineralized belts are controlled by anticlines in Zhenghe gold deposit and Shanyang-Fengzhen syn-sedimentary Fault is ore-directing structure to the deposit. Sulfur source is characterized with mixtures from mantle and crust. It is put forward that the mineralization have experienced hydrothermal sedimentation, deformal metamorphosis and tectonic superimposition stage in the deposit. |
