| 摘 要： | 通过阳山金矿带区域演化史的总结分析,结合西秦岭南部地区金矿成矿时代及其与造山运动的关系研究成果,对阳山矿带的区域成矿地球动力学体制进行了厘定;阳山超大型金矿和西秦岭地区大多数金矿床,特别是卡林-类卡林型金矿床,主要是在碰撞造山后期隆升伸展动力学体制下形成.通过对阳山矿带各种控矿因素的成矿作用分析与研究,认为各种控矿有利因素在相对局部的空间域内充分耦合是大型、超大型金矿成矿的重要条件.

| Abstract: | According to analyses of regional evolution history in the Yangshan gold belt, combined with research results of gold mineralizing time and its relationship with orogeny in the south area of western Qinling, regional ore -forming geodynamics system in the Yangshan ore belt has been defined. Yangshan super - large gold deposit and the most other gold deposits in the western Qinling, especially the Carlin - type gold deposits, were mainly formed in uplift and outspread dynamic system in the late collision orogeny period. Through the analysis and study of mineralization for all kinds of ore - controlling factors in the Yangshan ore belt, it is considered that coupling of all sorts of ore -controlling factors in relative local space has been significant condition to the mineralization of large and super -- large gold deposit. |
