Forekomsten sees som en fattig, rust-brun grafittskifer langs toppen av Raudhammeren i Myre kommune. Geofysiske helikopter og bakkemålinger viser at den mineraliserte er betydelig større enn det som er synlig |

Abstract: | |
Geological and geophysical investigations in Vesterålen were carried out during 2015 and 2016 with additional funds from the Nordland County Administration. A first report (Gautneb, et al., 2017) emphasizes the geological aspects of the graphite prospecting (trenching, sampling, analyses, mineralogy and beneficiation tests). This report describes the results from ground geophysical mapping of graphite mineralisations at five locations in the Vesterålen area. These are: Møkland (UTM 486848 – 7627365), Sommarland (UTM 488080 - 7625780), Kvernfjorddalen (UTM 488445 – 7619975) and Haugsnes (UTM 488600 - 7619375) in Bø municipality and Smines in Øksnes (UTM 498793 – 7639018) municipality. |

Abstract: | |
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. |

Abstract: | |
Several potential graphite occurrences in Vesterålen were selected for follow-up work based on helicopter-borne geophysical data. The purpose for this is to confirm the existence of the graphite and next to briefly evaluate the quality and quantity of the graphite-bearing structures. The goal for the project, which is sponsored by Nordland county administration, is to increase the knowledge of each individual graphite occurrence. By doing so, the interest in graphite prospecting in Northern Norway may increase, effective prospecting can be implemented, and land planning can be developed with appropriate regard for areas with potential for economic graphite. |

Abstract: | |
Artikkel i Minerals 2020 nr. 7 vol. 10. Abstract: There are three provinces in Northern Norway in which occurrences of graphite are abundant; the Island of Senja, the Vesterålen archipelago, and the Holandsfjorden area. From these provinces, we report graphite resources from 28 occurrences. We use a combination of airborne and ground geophysics to estimate the dimensions of the mineralized areas, and, combined with sampling and analysis of the graphite contents, this gives us inferred resources for almost all the occurrences. The average TC (total carbon) content is 11.6%, and the average size is 9.3 Mt or 0.8 Mt of contained graphite. We demonstrate that the Norwegian graphite occurrences have grades and tonnages of the same order of magnitude as reported elsewhere. The graphite-bearing rocks occur in a sequence that encompasses carbonates, meta-arenites, acid to intermediate pyroxene gneisses, and banded iron formations metamorphosed into the granulite facies. Available radiometric dating shows that the graphite-bearing rocks are predated by Archean gneisses and postdated by Proterozoic intrusions of granitic to intermediate compositions. |
