Quarzites retrieved from the Sopks-248 deposit and Belokamenka deposit, Antonovsk field cluster (Russia, West Siberia) were studied by the infrared spectroscopy method. The silicate thickness alteration rate was determined and the most crystalline quartzite variations were identified by defining the crystallinity index Ki according infrared absorption spectrum. To calculate "crystallinity index" the ratio of quintet peaks of 778 cm-1 as to peaks of 695 cm-1 were applied. It should be noted that the most crystalline quartzite variations are characterized by the relative value of crystallinity index.
