Argillizites of the torgashino limestone deposit

The article is devoted to argillizites found in limestones of the Torgashino deposit (the southern suburb of Krasnoyarsk) intersected by the pits to the depth of down to 200 m. The argillizites were examined by the methods of X-ray spectral element analysis, X-ray phase analysis and synchronous thermal analysis. They are referred to the ferriferous quartz-kaolinite type. Their fluidisateexplosive origin is substantiated. The formation of vein calcite onyx bodies in the process of low-temperature hydrothermal metasomatosis is associated with them.
