The Caledonian Mountain Chain of the Southern Troms and Ofoten areas. Part II. Caledonian rocks of igneous origin.

Abstrakt:

Metamorphosed rocks of igneous origin are described from Caledonian part of the Southern Troms and Ofoten areas. Based on megascopic and microscopic appearance, on chemistry and on field relations they can be divided into two separate groups whose age and geologic history differ from each other: The first group comprises serpentinites, amphibolites, meta-trondhjemites and metamorphozed quartz keratophyres. It is suggested that these rocks represent early peridotite intrusions, basalts, gabbros, basalt tuffs and tuffites, trondhjemite intrusives, and quartz keratophyre pytoclastics and lavas, respectively, all rocks having been metamorphosed by progressive regional metamorphism occurring during the Caledonian orogeny. Their mineral assemblages are generallly in good accordance with the distribution of metamorphic facies as this is revealed by the writer's previous investigations in adjoining metasediments. This first group represent the initial Caledonian magmatism in the area, largely belonging to the geosynclinal stage. The second group of igneous rocks includes ultrabasics (peridotites and troctolites), norites, gabbros, diorites, granodioritic and granitic rock types (to a smaller extent also trondhjemites). These rocks were only to a small degree altered by metamorphic processes.
