PGE {georefdatar}

Platinum-group elements – PGE

Description

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) ( ). In geochemistry, this group is further divided into two subgroups: Ir-PGE and Pd-PGE ( ) with Au often added to the latter (Rollinson 1993).

• PGE Platinum-group elements – e.g. ( ).

• IPGE, PPGE Ir-PGE and Pd-PGE – (Rollinson 1993, 1999);
