1.8 Ga magmatism in the Fennoscandian Shield; lateral variations in subcontinental mantle enrichment

A convergent continental margin setting with transpressional shearing was active during TIB formation in the west. Whether this shearing was instrumental in the formation of the 1.8 Ga magmatism further continentwards, or if the magmatisin in the central and eastern areas was the result of extension...

Description
Summary:A convergent continental margin setting with transpressional shearing was active during TIB formation in the west. Whether this shearing was instrumental in the formation of the 1.8 Ga magmatism further continentwards, or if the magmatisin in the central and eastern areas was the result of extensional collapse or plume activity is presently not known.
