Variations of platinum group elements in ultramafic ...

Platinum group elements (PGE), gold, and rhenium are the siderophiles which show contrasting geochemical distribution with lithophile elements such as rare earth elements. The PGE abundances are generally very low on the order of ppb or less in felsic rocks, and are relatively high in ultramafic rocks.

The ultramafic sills have the highest total noble metal content (46 ppb) followed by the magnesian basaltic suite (37 ppb) and the tholeiitic suite (21 ppb). The ultramafic sills are characterized by a relatively fiat chondrite-normalized platinum-group element pattern with an average Pt/Ir ratio of 3.52 and a pronounced Rh anomaly.
