| Abstract: | |
| Three main structural units are present: 1. The Precambrian (Svecofennokarelian) basement of the Børgefjell Window. ". Low grade (greenschist facies) Lower Paleozoic rocks belonging to the Seve-Køli Nappe Complex. 3. The higher grade (amphibolite facies) Helgeland Nappe, thrust on top of the low grade rocks. The bedrock lithologies within these units are briefly described. Metasediments, metavolcanics and intrusive igneous rocks are present in the Caledonian part of the sequence. Within the Precambrian, granite and granitic gneiss predominate but metasediments and rocks transitional between gneisses and the metasediments are common. The stratigraphical position of the Caledonian rocks is briefly discussed. |
