Concept

Pale yellowish-grey uniform sandstone with fine grain, partial flattening and orientation of constituent granules.
It is a porous rock whose interstices between the granules are only partially occupied by carbonatic concrete. It is formed predominantly by turbid crystal of Dolomite, by turbid carbonatic algae and by limpid calcite concrete. Less frequent are quartz, feldspars and fragments of metamorphic rock.
