| 摘 要： | 笔者将南秦岭卡林型－似卡林型金矿床与与其共生的热水沉积成因铅锌矿床，中国滇黔桂卡林型金矿床、卡林型金矿床命名地美国西部卡林金矿床、乌兹别克斯坦穆龙套型金矿床等进行了地质地球化学综合对比研究，可以发现，这些矿床的形成均与现代板块构造活动机制具有密切耦合关系，属于造山期成矿矿床，它们既具有相似特点：容矿建造属沉积岩型，沉积构造环境具有拉张裂陷性质，均显示同生一叠加改造两次成矿作用的特征；它们又具明显差别；所属大地构造背景不同，造山带组成及结构存在明显差别，叠加改造成矿作用表现的复杂和强烈程度差别较大，造山带区域构造演化与大规模成矿作用是同一大陆动力学过程的不同表现。

| Abstract: | In this paper an integrated geological and geochemical comparison is made of Carlin-para-Carlin type gold deposits in the South Qinling with their associated hydrothermal sedimentary lead-zinc deposits, the Carlin type gold deposits in the Yunnan-Guizhou-Guangxi gold triangle, China, the Carlin gold deposit, Carlin, western United States, and the Muruntau type gold deposit in Uzbekistan. The comparative study indicates that the formation of these deposits has an intimate coupling relation with the mechanism of the tectonic movement of modern plates. Therefore, these deposits belong to those that were formed in the orogenic stage. They have the following similar features: they are all sediment-hosted, occur in a tectonic environment of extensional rifting nature and show the features of syngenetic-modified mineralizations. On the other hand, they also have noticeable differences; they are different in respect to their tectonic settings, association and structure of orogenic belts and complexity and strength of the modified mineralization. The regional tectonic evolution and extensive mineralization in orogenic belts are different expressions of the same continental dynamic process. |
