Description:
This paper explores the unusual sulphide-graphite association of a selection of Beni Bousera garnet clinopyroxenites that initially equilibrated within the diamond stability field. Compared to common graphite-free garnet pyroxenites analysed so far, these rocks display tenfold S enrichment with concentrations up to 5550 μg/g. Fe-Ni-Cu sulphides (up to 1.5 wt.%) consist of large (up to 3 mm across), low-Ni pyrrrhotite (
