电气石的研究现状及其在地质学意义
Research Status of Tourmaline and Its Geological Significance

电气石是电气石族矿物的总称，以含B为特征的一种硅酸盐矿物。电气石凭借绚丽多彩的颜色在宝石市场上占有重要的地位。从19世纪末期开始，电气石电学性质的发现让学者展开了研究新热潮，而电气石具有独特的矿物学特征、地球化学性质等引来地质学家的关注，我国作为少有的电气石产出大国，对不同地区电气石的矿床成因研究已取得较大的进展。本文在前人研究的基础上初步概述了电气石的结构特征、物理性质、电学性质、分类、颜色成因等，通过矿床实例介绍了电气石的三种成因类型，最后结合全文探讨电气石在不同领域的应用研究，重点突出电气石在地质学领域中的应用及存在的地质意义。
Tourmaline is the general name of tourmaline minerals, a silicate mineral characterized by ele-ment B. It occupies an important position in the gem market with its brilliant and colorful colors. Beginning in the late 19th century, the discovery of tourmaline’s electrical properties led to a new wave of research. Tourmaline has unique mineralogical characteristics and geochemical properties, attracting geologists’ attention. As a rare tourmaline producing country, great progress has been made in the genesis of tourmaline deposits in different areas in China. In this paper, the structural characteristics, physical properties, electrical properties, classification and color origin of tourmaline are summarized on the basis of previous studies. Then this paper introduces three genetic types of tourmaline through examples of ore deposits, and finally discusses the application and research of tourmaline in different fields, focusing on the application and geological significance of tourmaline in the field of geology.
