• The lowermost part of the Amasined sulfide occurrence in the Beni Bousera ultramafic massif consist of clusters of subidiomorphic or corroded chromite crystals and radial fractured, rounded aggregates of nickel arsenides included in a Fe-Ni-Cu sulfide groundmass. This textures is interpreted in terms of gravitational differentiation of an immiscible Ni-As-based magmatic melt in a chromite-bearing sulfide melt.
