Platinum-group element geochemistry of strongly differentiated magmatic complexes: examples from the Bohemian Massif

Highly siderophile character of platinum-group elements gives a powerfull tool for the study of upper mantle, magmatic intrusions and volcanic flows differentiation. Strongly differentiated intrusions shows an excellent possibility for the study of trace element behaviour during magmatic differentiation and fractionation. This project is focused on behaviour of platinum-group elements during differentiation of gabbro-peridotite and gabbro-diorite intrusions (as will be demonstrated on the Ransko, Kdyně, Poběžovice, Mutěnín and Drahotín intrusions from the Bohemian Massif) on the basis of their distribution in particular rock types and mineral phases (silicates, oxides and sulphides).
