| 摘 要： | 在萤石矿床类型划分的基础上,根据萤石矿床的大地构造背景、分布特征、成矿条件和控矿因素,文章划分了中国萤石矿床的成矿区带,并对每一个成矿区带的成矿特征做了简述;总结了中国萤石矿床成矿规律。中国萤石矿床集中分布于北部和东南部,断裂是各种矿床类型共有的必要成矿要素。沉积改造型萤石矿床的形成与灰岩和火山岩有关;与萤石矿床形成有关的侵入岩绝大部分为燕山期侵入岩;无论是沉积改造型、热液充填型还是伴生型萤石矿床,大型、特大型萤石矿床的形成多与灰岩有关。同时具备灰岩、燕山期侵入岩和断裂成矿三要素的矿床多为大型、特大型萤石矿床。中国萤石矿床的形成集中于燕山期。

| Abstract: | Abstract: Based on the classification of fluorite deposits, this paper divides the metallogenic units of fluorite deposits, and briefly describes ore-forming features of every unit according to the geotectonic background, distribution features, ore-forming conditions and ore-controlling factors. In addition, the metallogenic regularities of fluorite deposits in China are summarized. Fluorite deposits are mainly distributed in northern and southeastern China. The faulted fractures constitute the common and essential ore-forming factor. The deposition-reformation type fluorite deposits are genetically related to limestone and volcanic rocks. The most intrusive rocks related to the formation of fluorite deposits belong to Yanshanian period. Most deposition-reformation, hydrothermal-reformation, associated, large and gigantic fluorite deposits are genetically related to limestone. The deposits with three ore-forming elements of limestone, Yanshanian intrusive rocks and faulted fractures are generally large or gigantic fluorite deposits. Fluorite deposits in China were mainly formed in Yanshanian period. |
