Abstract:In order to study the spectral characteristics and color-genetic mechanism of the scheelite with orange color found in scheelite-tin-beryl (W-Sn-Be) deposits in Xuebaoding, four groups of scheelite were investigated by means of EMPA, IR, LRM and XRD. The scheelite samples were tested by XRD and IR in order to reveal if there are other minerals intermingled with scheelite. Meanwhile, the structure, the structure water and the crystal water were studied through infrared spectra. The absorption bands and peaks of infrared and Raman spectra were assigned. Finally, it seems that there is no distinct color difference between scheelite from Xue baoding and those from other places. So, it is conceived that the color causing may correlate with the minor crystal structure, trace element or REE in the crystal.
