K-feldspars in pegmatites from Luc Yen gem mining area, Yen Bai province, Vietnam were studied by X-ray fluorescence, X-ray powder diffraction and the Raman spectroscopy. Chemical analysis determined the K-feldspars in the form: of (K_{0.8909}Na_{0.0388}Ca_{0.002}Pb_{0.0042}Cs_{0.0024}Rb_{0.0338})(Al_{0.9975}Fe_{0.0053}Ti_{0.0004})Si_{2.988}O₈. Both X-ray powder diffraction and Raman spectroscopy indicated Luc Yen K-feldspars as orthoclase phase. Together with the values of Al content of the T1 tetrahedral sites in orthoclase, it is understood that Luc Yen pegmatites are of young ages (Cenozoic) and shallow intrusive types.
