The geology of the Engebøfjell eclogite deposit and its regional setting

Abstract

Fortrolig til 04.05.2003. The Engebøfjellet eclogite deposit is situated at the northern side of Førde- fjord near the small community Vevring in Naustdal kommune, Sogn og Fjordane county, W.Norway. Geologically the Førdefjord area belongs to the \"Western Gneiss Region\", between the Devonian Kvamshesten basin to the south and the Devonian Håsteinen basin to the North. Recent mapping divide the Førdefjord region into two major geologic units: the Hegreneset complex and the Helle complex. The Hegreneset complex (oldest) contains a variety of amphibolite, eclogite and gabbroic rocks, together with tonalitic to dioritic gneisses. The Helle complex comprises mainly granitic and granodioritic gneisses.
