Minerals found during construction of a new road tunnel (Heggur tunnel) in the beginning of the 1980s (1982) (which was named as the "Tafjord tunnel" during the construction period).

Pumpellyite-(Fe2+) and an assemblage of various other minerals are reported in fissures in a Precambrian granitic gneiss situated between Tafjord and Fjøra (Brastad, 1984).

"The wallrock for these mineral occurrences is a light red, granitic Precambrian gneiss with low or medium grade mineral assemblages. The normal
mineral assemblage is K-feldspar + plagioclase + quartz + hornblende ± biotite ± Fe/Ti-oxides. The gneiss encloses also a number of meta-eclogites with relics of assemblages formed during high pressure metamorphism (Brueckner 1977)." (Brastad, 1984).
