近三年来,作者在研究河北寿王坟铁多金属矿床的蛇纹石族矿物的过程中发现了若干含氟量较高的蛇纹石,经过室内工作肯定的有氟叶蛇纹石(Fluorantigorite)和氟纤维蛇纹石(Fluochrysotile)。报导过的氟叶蛇纹石系其中之一,该矿物是受过轻微蚀变(叶蛇纹石化)的矿物种,其化学成分和物理性质较原始者有所变异。本文将新获得的未遭蚀变的氟叶蛇纹石和新发现的氟纤维蛇纹石一并作一简介。蛇纹石族矿物是一族常见的造岩矿物。过去对它们的化学成分很少分析氟,近年来虽然有人已开始注意,但所分析矿物的含氟量约在千分之几。氟叶蛇纹石和氟纤维蛇纹石的含氟量却达百分之几。同时,它们的某些特性,象颜色、折射率、硬度和产状等同一般相应的矿物种有明显差别,所以,该
In the past three years, the authors found some serpentine with high fluorine content in the study of serpentinite minerals from the Shouwangmu iron-polymetallic deposit in Hebei Province. Fluorantigorite ) And Fluocrysotile. One of the reported fluoro-leaf serpentines is that the mineral is a slightly altered (leaf serpentine) mineral species with a variation in its chemical composition and physical properties as compared to the original one. In this paper, a newly introduced non-altered fluorine leaf serpentine and newly discovered fluorine fiber serpentine are briefly introduced. Serpentine minerals are a group of common rock-forming minerals. In the past, fluorine was rarely analyzed for their chemical composition. Although some people have started to pay attention to it in recent years, the content of fluorine in the analyzed minerals is about a few thousandths. Fluoride serpentine and fluorine fiber serpentine fluorine content is up to a few percent. At the same time, some of their characteristics, such as color, index of refraction, hardness and appearance of the corresponding mineral species are obviously different, so the
