Clintonite is a rare type of brittle mica (calcium analogue of phlogopite). Its new find in Urals is described. Clintonite is a part of garnet clinopyroxenite, composing a block-inclusion in a serpentinite melange. Geological conditions in which are clintonite-bearing rocks of Urals are considered. The conclusion is drawn on the most probable magmatic, instead of metasomatic, their genesis. The first are resulted for Urals clintonites infrared and raman spectrums.
