中文摘要:重晶石全球范围内广泛分布,重晶石矿床具有形成时代多、元素来源复杂、成矿作用多样等特点,目前有关重晶石矿床的成因仍存在争议。文章系统分析前人的研究成果,厘定了不同类型的典型矿床、成矿时代规律,探讨了不同类型矿床中成矿元素来源、成矿作用及成矿机制。矿床类型方面,重晶石矿可分为沉积型、岩浆热液型、层控型、火山-沉积型和风化(残积)型,主要分布在特提斯成矿域和劳亚成矿域,其他地区主要是冈瓦纳成矿域和环太平洋成矿域,其中沉积型是最主要的成矿类型,占重晶石矿床的60%以上。成矿时代方面,重晶石的成矿时代主要为古生代和中生代,赋矿岩系以沉积岩为主,其次为岩浆岩。成矿物质来源方面,全球典型重晶石矿床中的S同位素和Sr同位素显示,成矿物质来源具有多源性、多样性、差异复合性等特点。成矿机制方面,重晶石的成矿机理复杂,具有多阶段性、多因素等特点。
Abstract:Barite deposits are widely distributed in the world which have the characteristics of multiple formation ages, complex element sources and diverse mineralization. At present, the genesis of barite deposits is still controversial. This paper systematically analyzes the previous research results, determines different types of typical deposits, metallogenic age, and discusses the source of metallogenic elements, mineralization and metallogenic mechanism in different types of deposits. In terms of deposit types, barite deposits can be divided into sedimentary type, magmatic hydrothermal type, stratabound type, volcanic sedimentary type and weathering (residual) type. It is mainly distributed in Tethys metallogenic domain and Laurasia metallogenic domain. Other regions are mainly Gondwana metallogenic domain and circum Pacific metallogenic domain. Sedimentary type is the most important metallogenic type, accounting for more than 60% of all barite deposits. The metallogenic ages of barite are mainly Paleozoic and Mesozoic, and the ore bearing rock series is mainly sedimentary rock, followed by magmatic rock. In terms of ore-forming material sources, S and Sr isotopes in typical barite deposits around the world show that the ore-forming material sources are characterized by multi-sources, diversity and differential compounding. In terms of ore-forming mechanism, the ore-forming mechanism of barite is complex, with multi-stage and multi factor characteristics.
