BEOLA ARGENTATA

This is an orthogneiss deriving from the stratum of Monte Leone in the "radical zone". It presents a very pervading and regular foliation, accentuated by lepidoplasts of white (muscovite) and black (biotite) mica. It does not present real gneiss layering with a clear separation between quartz and feldspar lenticulars and films or packets of micas. The homegeneous fine texture, the reduced grain of the mineral elements and the abundance of clear mica confer the stone a light grey colour with very particular silver reflections.
