萤石成矿机制的探讨

对萤石成矿物质的物理化学性质、矿物流体包裹体化学成分、萤石矿物不同颜色的原因、光学萤石与晶洞的相关性和主要共、伴生矿物组合的研讨，结合其成矿的地质背景，认为：在地球内部单质氟（F2）不可能存在；气态SiF4是氟的主要迁移形式；SiF4与CaH2一道从地球深部随岩浆、热气迁移至地壳浅部，被氧化、分解成矿。或与围岩、热液中有关成分作用成矿。

An Approach to the Ore- forming Mechanism for Fluorite Deposits

This paper deals with physical and chemical properties of ore material from fluorite deposits, chemical composition of fluid inclusions in fluorite, colors of fluorite, optical fluorite and its associated minerals in vugs. Above-mentioned and ore-forming geological setting suggest that there is no free fluorine (F_2) as simple substance in the Earth, most of fluorine migrates as gaseous SiF_4, and SiF_4 with CaH_2 along with magma and hydrotherm migrate from deep Earth to the upper level, and is oxidized and decomposed or interacted with wall-rocks or other compositions in the hydrotherm, resulting in the ore-formation.
