Ru-Pd and Os-Pt: in chemistry, this group is referred to as the platinum
metals. Since the 1960 geologists are using the term "platinum-group
elements" (PGE) \insertCiteMarshall1999,Connelly2005georefdatar. In
geochemistry, this group is further divided into two subgroups: Ir-PGE and
Pd-PGE \insertCiteMarshall1999georefdatar with Au often added to the
latter \insertCiteRollinson1993georefdatar.
