摘要
软玉具有多种颜色,类质同象替代导致颜色多样性。通过红外光谱、X射线衍射检测软玉,发现各色软玉同种检测谱图总体形状基本相同,说明软玉主要是由透闪石组成。通过对各种颜色软玉化学成分进行分析,说明软玉主要致色因素是铁,铬与锰也有一定影响,墨玉主要是含石墨包体所致。
Nephrite presents in many different colors which is resulted from isomorphous replacement. Adopting infrared absorption spectrum, X-ray diffraction to test nephrite, it has found that the nearly same spectrum of nephrite with different colors caused by the same testing method indicates that the major mineral which composes nephrite is tremolite. According to the analysis on chemical composition of nephrite with different colors, it has concluded that the major coloring element of nephrite is Fe with some Cr and Mn elements affection. Black nephrite is led by graphite inclusion.
