[Study on the spectra of granite of asbestos red and sesame white]

In this paper, the composition and spectra of granite of asbestos red and sesame white are studied by ICP-AES, XRF, IR and X-ray diffraction. According to the X-ray diffraction, the components were determined by computer. Comparing results, it is concluded that the red colour of asbestos red granite is caused by the red minerals of Fe contained in it.
