The Gour Oumelalen area exposes Paleoproterozoic (1.9 Ga) marbles and calcsilicate granulites. Some marbles show a specific mineralogy characterized by the presence of a highly aluminous clinopyroxene with Al 2 O 3 content exceeding16 wt%. This clinopyroxene shows a marked zoning with a hedenbergitic core rimmed by fassaite.
