| 摘 要： | 以辽宁省岫岩县桑皮峪新近发现的透闪石玉矿为研究对象,运用现代测试方法,如岩相学观察、矿物化学分析、同位素分析等,对桑皮峪透闪石玉的玉石学特征、矿物组合、化学成分等做了较为系统详细的研究.结果表明桑皮峪透闪石玉主要由隐晶质和细晶质透闪石集合体组成,透闪石含量在94%以上,杂质矿物主要有磷灰石、绿泥石、绿帘石、蛇纹石、方解石、褐铁矿等.根据对桑皮峪透闪石玉的各种分析测试资料和成矿地质背景进行综合分析,桑皮峪透闪石玉的矿床成因类型可以定为变质热液矿床.

| Abstract: | In this paper, a new nephrite deposit was reported from Sangpiyu Village of Xiuyan County, and an analysis of its gemological characteristics, mineral assemblage, chemical composition was carried out. Modern techniques such as microscope, electron microprobe analysis, chemical analysis, and isotope analysis were employed. The results show that the nephrite from Sangpiyu is mainly composed of tremolite (> 94%), with minor apatite, chlorite, epidote, serpentine, calcite and limonite. Tremolite texture is characterized by microcrystalline-cryptocrystalline aggregates. It is concluded that the nephrite deposit in Sangpiyu Village is a kind of metamorphic hydrothermal deposit. |
