Abstract

Sm-Nd dating of minerals in several Norwegian country-rock eclogites reported here indicates that the rocks crystallized ∼425 Myr ago. The isotopic composition of both Nd and Sr in these eclogites suggests that they formed from much older crustal rocks. The high-pressure metamorphism of which the eclogites are relics probably involved subduction of the continental Baltic plate as it was overridden by the Greenland plate during the Caledonian orogeny.
