氟镁石(Sellaite)是一种比较罕见的矿物。1868年首次发现于法国,它产于冰碛层中的白云岩内,与石盐和硬石膏等共生。此后,在意大利维苏威火山喷出岩空洞中见到它与硬石膏、石膏等共生。它作为高温热液的矿物,出现于钼、锡和锡-铍矿床中,常与萤石共生或与石英共生;在铅锌矿床中,与金云母、黄玉和电气石等共生;在盐类矿床中,与硫、石膏,萤石共生。国内曾对钨矿中的氟镁石进行过较详细的工作。1980年我队在含金多金属矿脉中见到较多的氟镁石,它与金矿密切相关。本文拟对其产状、物性和组成等方面进行简要的报道。
Sellaite is a relatively rare mineral. First discovered in 1868 in France, it is produced in dolomites in the moraine layer and is symbiotic with rock salt and anhydrite. Since then, it has been seen in Italy’s Mount Vesuvius spray rock and hollow with anhydrite, gypsum and other symbiosis. It occurs as a hydrothermal mineral in molybdenum, tin and tin-beryllium deposits, coexists with fluorite or coexists with quartz, coexists with phlogopite, topaz and tourmaline in lead-zinc deposits, Deposits, and sulfur, gypsum, fluorite symbiosis. In China, there have been more detailed work on the magnesite in tungsten ore. In 1980, the team saw more fluorite in the gold-bearing polymetallic ore veins, which is closely related to the gold mine. This article is intended to give a brief account of its production, physical properties and composition.
