This report describes 21 graphite occurrences in the Lofoten-Vesterålen area, including reviews of previous graphite investigations, the geological setting and analytical data related to analyses of graphite in the described occurrences. The graphite occurrences are situated in high-grad Archaean metamorphic rocks comprising quartzites, intermediate and mafic gneisses, iron formations, dolomites and graphite schist. This suite of rocks is intruded by a number of igneous complexes, mainly intermediate to acid charnockitic rocks and granites. 64909
