Abstract
Norwegian gneiss eclogites are formed in situ within the temperature–pressure range 300–800 °C, 8–22 kbar. The regional KD(FeO/MgO)ga+cpx distribution pattern indicates an increasing P–T trend towards the coastline. Retrograde reactions indicate a nearly isothermal uplift history. A plate tectonic model, involving continent–continent collision and subduction is proposed for the formation of these eclogites.
