The high-pressure metamorphosed Gridino dyke swarm comprises a major group of Mesoarchean 2.87-2.82 Ga mafic dykes intruded within the Mesoarchean continental crust of the Kola craton(the Belomorian tectonic province
Two eclogite associations have been recognized within Belomorian TTG gneisses:(1)the subduction-type Salma association and(2)Gridino eclogitized mafic dykes.Protoliths of the Salma eclogites represent a sequence
