在前人研究的基础上,根据台湾软玉的地质产出及矿物组成特征,利用偏光显微镜对其样品的结构构造进行研究,结果表明:台湾软玉的主要矿物成分为透闪石,透闪石主要呈毛毡状变晶结构,其形成可分为四个世代.第一世代为束状放射状,不定向排列；第二世代为柱状,穿插生长于第一世代透闪石中,在柱状透闪石间产出有碳酸盐矿物；第三世代为毛毡状集合体,它是质量较好的软玉的主要结构；第四世代为平行纤维状,具此结构的软玉能表现出良好的猫眼效应.%Based on the previous studies, the authors employed polarized optical microscope to study the geological features and mineral compositions of the nephrite samples from Taiwan province in this paper, the results indicate that the samples from Taiwan province are composed mainly of tremolite and the major texture is felt-like blastic texture. Tremolite went though four different generations: the first is bunchy or radial, not parallel to each other; the second is prismatic, interspersed among the first generation, between the prismatic temolites there are some carbonate minerals; the third is felt-like, witch is the best quality of the Taiwan nephrite's structure; the fourth is parallel fiber-shaped, with witch the nephrite can show good cat's eyes effect.
