Abstract
Post-collisional layered syenite complex is exposed in the Sør Rondane Mountains, eastern DML. The syenite complex has been derived from the high-K alkaline magma, and fractional crystallization and accumulation play an important role of formation of the layered structure. The present result demonstrate that the Sør Rondane Mountains underwent the extensional collapse similar to that observed in other part of DML.
