Description
Summary:The genesis of platineferous low-sulfide rocks in the Kivakka layered intrusion in Northern Karelia was investigated. Data demonstrate that the additional emplacement of more primitive magma during the crystallization of the intrusion could temporarily stop the segregation of the sulde phase, because the magma returned to its lower fractionation steps.
