| 文石矿物学特征及文化研究 摘 要 文石是近几年来玉石市场上越来越受关注的矿物品种，但还未得到珠宝玉石相关地开发利用，知名度较低，也因此关于它的矿物学特征研究匮乏。本文将利用部分宝石学常规仪器及大型仪器的实验测试数据，结合文献研究法、观察法、 实验研究法对同一产地不同外观、市场上主要流通颜色的文石进行矿物学特征、谱学特征进行研究。 云南文石的颜色以白色、蓝绿色为主；透明度从透明到半透明；光泽从玻璃光泽；非均质体，晶簇状、纤维状、钟乳状集合体；折射仪远视法测试折射率值为 1.60（点测）；带密度组件的电子天平测试相对密度约为 3.00；紫外荧光仪测试结果呈惰性；断口为贝壳状断口。通过傅立叶变换红外光谱仪测试发现文石样品标本在中红外光谱区中发现具有鉴定意义的碳酸根离子振动导致的特征红 外吸收谱带。本文中文石样品标本主要矿物成分为碳酸钙。 文石产地众多，是比较常见的矿物之一，通常分为澎湖文石、景文石、红文石三大类。澎湖文石色彩鲜艳，质地优良，有天然的“猫眼”；景文石具有大自然鬼斧神工的自然美，图纹色彩多，纹理复杂多变，图纹内容丰富，艺术造型奇妙；粉红色系的红文石，阿根廷红文石间有乳白色条纹，被赋予高贵纯粹的寓意。 关键词：云南省；文石；晶簇状；矿物学 Abstract The agateonite is the mineral variety which in the jade market more and more receives in the last few years looks after, but has not obtained the jewelry jade to develop the use related, well-knownness is low, also therefore is deficient about its mineralogy characteristic research.This article will use the partial gemology convention instrument and the large-scale instrument experiment test data, the union literature methodology, the method of inspection.The experimental methodology to in the identical habitat different outward appearance, the market the main circulation color agate carries on the mineralogy characteristic, the genealogy characteristic conducts the research. Yunnan Province agateonite color by white, cyan color primarily; Transparency from transparently to translucent; Gloss from glassy luster; Heterogeneous body, drusy, fibrous, stalactitic aggregate; The refractometer hyperopia law test refractive index value is 1.60 (spot measures); The belt density module electronic balance test relative density is approximately 3.00; The ultraviolet luminoscope test result assumes the inertia; The fracture is the conchoidal fracture.The discovery has the characteristic through the Fourier transformation infrared spectroscope test discovery agate sample specimen in the infrared spectrum area which the appraisal significance carbonic acid radical ion vibration causes infrared absorption band.In this article the agate sample specimen essential mineral ingredient is the calcium carbonate. The agateonite habitat is multitudinous, is one of quite common minerals, usually divides into the Penghu agateonite, the scenery agate, the red agate three big kinds.The Penghu agateonite color is bright, the quality of material is fine, has “the cat eye” naturally; The scenery agate has the nature clever axe finger of God natural beauty, attempts the grain color to be many, texture complex changeable, attempts the grain content to be rich, the artistic modelling is marvelous; The pink department's red agate, has the cream color stripe, entrusts with the noble pure implication.
