dc.description.abstractIn the northern Iveland-Evje area extensive magmatic activity occurred during the so-called Sveconorwegian igneous period. Two intrusive episodes can be distinguished through apparently they occurred close in time. The oldest intrusions are represented by amphibolites which were emplaced under plutonic conditions and thus were able to deform the gneissic host rock (globulitic type of intrusion). At the close of this first episode basic dykes were intruded. During the second episode monzonite and granite were intruded, followed by monzonitic conical sheets and radiating dykes. Aplitic dykes and pegmatites brought the igneous activity to a close.
