Første gang mutet av Lund i 1902. Det er litt usikkert om dette er det aktuelle skjerpet. Det er utsprengt her, men grunnen kan ha vært å planere ovarennet til en gammel hoppbakke. (Steinhoppet står fortsatt lenger ned.) Bergarten er en fin- til middelskornet amfibolitt med små, lyse granittiske utsondringer. Amfibolitten mangler målbar foliasjon, men er oppsprukket i flere retninger. Magnetkis og kobberkis er ujevnt disseminert over de få m2 som er blottet (prøvene 01, 02 og 03). Grovkornet syenitt er blottet like ved. |

Abstract: | |
From a structural point of view the bedrocks of the map area can be subdivided into 1. Precambrian basement (autochthonous), and 2. Allochthonous Caledonian units. The Caledonian sequence embraces a) The lowermost over-thrust units, b) The main unit (Harstad Nappe) and c) The upper units (Straumsbotn Nappe and Niingen (?) Nappe). The main unit belongs to the Seve-KÎli Nappe Complex. The bedrock lithoogies within these units are briefly described. Metasediments, metamorphosed igneous intrusive rocks and possible metavolcanics (some amphibolite layers) are met with in the allochthounous sequence together with deformed Precambrian granite. Within the autochthonous Precambrian, granite and granitic gneiss predominate although meta-gabbro covers a large area in the northwestern part. Ore occurrences (magnetic ore, copper etc.) of the "skarn type" are connected with inclusions of metasediments (marble, mica schist etc.) in the Precambrian granite. The deformation history of the area can be subdivided into 3 episodes (F1, F2, F3) of which F1 and F2 are the most important ones. F1 resulted in mainly recumbent folds with an axial plane schistosity. This F1 schistosity is the regional schistosity now observed. |
