摘　　要：锑矿床研究的重点包括 :锑矿床分类 ;不同构造环境下锑矿床的成因模式 ;锑的来源。今后锑矿床分类将以锑矿床形成的构造背景为主 ,结合锑矿床成因方式和容矿主岩特点来进行。文章介绍了几种典型构造环境下 (大型走滑、造山挤压和造山崩坍 )锑矿床形成机理和成因模式。现有的资料表明锑矿床受壳幔相互作用所制约 (如拆沉作用 ,delamination) 。The most important problems in the study of antimony deposits include classification of antimony deposits, genetic models of antimony deposits in various tectonic settings, and antimony sources. In further classification of antimony deposits, we should consider tectonic settings, origin of antimony deposits and host rocks. This paper deals with genetic models of antimony deposits in different tectonic settings. The data of antimony deposits indicate that the formation of antimony deposits is controlled by such interactions between the crust and the mantle as delamination. This seems to be the most important and difficult problem.
