Abstract
Noble metals, sulfur and copper provide a means of distinguishing betw een layered gabbros and intrusive ultramafic rocks making up the pluto nic sequence of the ophiolite of Oman. The layered gabbros have mantle -normalized patterns with a positive slope between lr and Pd, and are very poor in noble metals relative to S and Cu (S/Pd(MN) and Cu/Pd(MN) > 1). The ultramafic intrusions, very poor in S and Cu, have flat to arch-shaped normalized patterns (Cu/Pd(MN) = 0.1-0.02) without signifi cant fractionation from Ru to Au.
