There are abundant rare metals such as Li, Nb, Ta, Rb, Cs and Be in granitic pegmatites of Lushi County, Henan Province. The authors made a systematic study of mineralogical characteristics of spodumene from Guanpo pegmatites in Henan Province by such means as hand specimen and microscopic observation, X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray fluorescence analysis and ICP-MS. According to hand specimen and microscopic observation, the main mineral compositions of spodumene-bearing granitic pegmatites are spodumene, quartz, feldspar and muscovite. Regional geological geomorphology of this area shows that spodumene was crystallized later than plagioclase in the course of magmatic differentiation. The results show the content of Li2O in spodumene has reached industrial grade. Spodumene is an important ore material for lithium exploration in this area.
