ESR STUDY of "GUIZHOU JADEITE"

Cai Xiucheng Cao Junchen Fu Yude Tang Rongbin (Institute of Geochemistry, Academia Sinica, Guiyang)  
"Guizhou jadeite", a gem stone, has been investigated by ESR. It is a superposed spectrum of white quartz,green dickite and organic substance. The paramagnetic centers in "Guizhou jadeite" are radiation center in quartz (g 2.01);Fe_1~(3+)(g_⊥=4.03,g〃=4.26),Fe_2~(3+)(g_⊥=3.41,g〃=3.18) and VO~(2+)(g_⊥=1.981,g〃=1.938, A_⊥=64.3G, A〃=185.4G) in crystal structure of dickite; organic radical and so on. It is shown again that the blue-green color of "Guizhou jadeite is caused by Cr~(3+) in dickite.
