Summary:This deposit is rich in PGE and occurs in the basement beneath the Kilvenjärvi block of the Portimo layered complex; sulphide mineralogy, petrography and Re-Os isotopic values establish that there is a close connection between the Portimo complex and the PGE deposit. It is considered that the deposit formed from a PGE-rich sulphide liquid which separated from the Portimo magma during differentiation and leached out through the margin of the intrusion into the basement.
