I ura er det endel blokker nedrast fra stupet av en finkornet gabbroid bergart med ilmenitt-magnetitt-disseminasjon (prøve 01 og 02) og tildels semimassive oksydpartier. Mineraliseringen må opptre et sted i dette stupbratte fjellet, like ved kontakten til intruderende ultrabasitt, som i nærheten fører Ni-Cu-mineralisering (Småvatna og Bonjikdalen). Søyland Hansen (1971) har også funnet ilmenittanrikning med disseminerte sulfidkorn i en pyroksenittisk, gabbroid bergart SØ for Storvatnet (mineralisering 1). (Søyland Hansen benevner Storvatnet for Stålvatnet, hvilket var ukjent for lokalbefolkningen i Reinfjord.)

Abstract:

General descriptions of the different metasediments, metavolcanics and igneous rocks within the map area are presented. Three principal map-subdivisions are recognized; (a) supracrustal Precambrian (Karelian) rocks occurring in tectonic Windiws; (b) autochthonous late Precambrian to Lower Cambrian (meta)sediments; and (c) a thick allochthonous nappe-complex od Eocambrian to Cambrian metasediments, gneisses and various igneous rocks. In addition to these lithologies, sediments of unknown age (but possibly Silurian) lying unconformably upon allochthonous gneisses are noted from the south-western corner of the map-sheet. Descriptions are given of the many types of plutonic rocks occurring within the Seiland-Stjernøy petrographic province. These include several varieties of gabbro as well as diorites, peridotites, syenite, nepheline syenite, hornblendite, carbonatite, anorthosite, trondhjemite and adamellite. The major tectonic structural subdivisions of the map-area are outlined and it is shown that the matamorphic lithologies of the allochthon, here referred to as the Kalak nappe-complex, can be readily separated into three main tectonic units, or nappes.
