The chemical composition and spectra characteristic of feldspar from Zhoukoudian granodiorite were systematically analyzed. Based on the field work, some feldspar samples were selected for crystal chemistry and structure analysis through EMPA, IR, LRM and XRD. The compositions of the feldspar range between Ab (85.21) Or (0.18) An (9.11) and Ab (90.06) Or (3.00) An (13.27) by electronic microscope probe analysis. According to the XRD peak and its diffraction intensity, the mineral species was found the unit cell parameters were calculated. The absorption bands and peaks of infrared and Raman spectra were also assigned and the results show that the characteristics of its infrared and Raman spectra are in accordance with the ideal atlas of albite. The infrared spectra show that all the analyzed feldspar grains contain structural hydrogen, which occur as OH-. On the basis of the above analyses, the crystal chemistry and structure characteristics of feldspar were summarized.
