摘要 云南麻栗坡祖母绿晶体粗大,颜色呈黄绿至翠绿色,少数呈蓝绿色。其钒含量(V2O3为0.08%~1.83%),明显高于世界上其它产地的祖母绿。光吸收谱研究表明其颜色是由Cr3+、V3+、Fe2+及Fe3+过渡金属离子综合作用引起的。云南祖母绿开发前景可观,是一种很有价值的宝石和矿产资源。 The emerald crystals from Malipo of Yunnan are of big size.Their colors vary from yellowish green to fresh green,and a few are bluish green,It is shown by the study that the Yunnan emeralds contain obvious higher vanadium (V_2O_3:0.08-1.83%) than those from other locations in the world.The study of optical absorption spectra shows that the colors are caused by comprehensive effects from the transition metal ions:Cr^3+,V^3+,Fe^2+and Fe^3+.The exploitation perspective of Yunnan emerald is quite bright as a valuable gemstone and mineral resources.
