Abstract

The work presents a detailed mineralogical characteristic of the Fuchsite meta-sandstone of the Stoilenskaya suite of the Kursk series KMA. The rock-forming and accessory minerals are characterized. The development of fuchsite (K(Al,Cr)3Si3O10(OH)2) in metasedimentary rocks has been established due to dehydration of hydro-mica and decomposition of ferro-chromite detrital crystals under conditions of epidote-amphibolite facies of the metamorphism.
