Abstract
The chromite-Ni arsenide mineralizations from the Beni Bousea ultramafic massif show secondary arsenide (maucherite, orcelite) and silicate (phlogopite, chlorite, vermiculite, garnierite) associations originates by a progressive hydrothermal alteration of the primary paragenesses. According to field and textural relationshisps this hydrothermal alteration should take place coeval with late brittle fracturing of the peridotites.
