Forekomsten ligger på sørsida av Storbekken i glissen bjørkeskog ca. 860 moh. Enkleste adkomst er langs en sti som går på nordsida av bekken. Berg (1917) omtaler forekomsten som del av et felt som utgjøres av Løken - Estenmoen (mulig HE0118 Bjørkeng) - Orkelbogen, og den er benevnt Kvikne 12 & 13 på eldre kart (Bredesen 1903). Hovedforekomsten består av en 5 x 5 m vannfylt grop med en dels begrodd 60 m3 stor tipp omkring. Malmsonen er ikke blottet i hovedskjerpet men kan følges stedvis mot et mindre skjerp som ligger 50 m lengre nordøst (Lykkja skjerp), hvor sonen har retning 60°/30°. Malmsonen overlagres av finkornet amfibolitt som dels er noe skifrig og klorittisert. Kalkførende biotittskifer ligger både over amfibolitten og under malmsonen. Bånding og skifrighet i denne er 27°/35° og 52°/35°. Massiv og semi-massiv magnetkis dominerer (prøve .04 og .02), og i tillegg finnes intenst årenettverk av magnetkis, dels sammen med pyritt og spor av kobberkis og sinkblende (prøve .01 og .03). Grunnmassen er kvarts- og/eller klorittrik. Mineraliseringen har flere likhetstrekk med Børsjøhø-forekomsten (HE0117) som ligger ca. 5 km lengre mot sørsørvest. |

Caledonian sulphide deposits and minor iron-formations from the southern Trondheim region, Norway. |
;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU; No.340;35-85 + k pages |
Abstract: | |
Within the southern and central parts of the Trondheim region of the Norwegian Caledonides a great number of small, stratabound cupriferous pyrite deposits are confined to mafic metavolcanics of the Gula, Støren and Fundsjø Groups of the Lower Palaeozoic succession. The deposits occuring within, or in close contact with the metavolcanics are characterized by their association with minor manganiferous oxide/silicate iron-formations - better known as "vasskis" ore type - within the metamorphic low-grade areas. The iron-fprmations of the metamorphic higher grade terrains on the other hand, which are extensively developed within the Gula Group, are mostly of a pyrrhotitic sulphide/silicate type and sulphurization processes are thought to have played an important role during the metamorphism. The pyrite deposits occurring adjacent to the metavolcanics bear no relationship to the iron-formations. They are embedded in pelitic, often carbonaceous assemblages (Gula Group) or within tuffitic members of the volcanogene Støren Group, and they are thought to represent re-sedimented (reworked) deposits. The pyrite deposits display varying degree of metamorphic reconstitution and a tectonic control has apparently determined their disc- or ruler-shaped morphology. |

Abstract: | |
Rapporten beskriver følgende forekomster: - Sæterfjellets kisfelt som opptrer som en rekke ganger med stor regelmessighet og med mektigheter fra en til ti meter. Malmmineraliseringen er kobberholdig svovelkis. - Sandfjellets kisfelt, forekomstene er lite undersøkt. - Løken, Estermoen og Orkelbogen er et ca 10 km langt felt med betydelige mektigheter. |

Nordøst for hovedforekomsten er det flere små hull og påhugg. Det største av disse er kalt Lykkja skjerp og består av et 2 x 2 m vannfyllt skjerp med 20 m3 tipp som er svært begrodd. En 30-40 cm bred malmsone med retning 60°/30° er blottet i det sørvestre hjørnet av skjerpet. Den opptrer mellom amfibolitt og kalkførende biotittskifer. Mineraliseringen er lik malmen i hovedforekomsten, men i tillegg finnes også pyrittrik malm med små mengder arsenkis, kobberkis og sinkblende i en kvartsrik grunnmasse (prøve .05). Spor av arsenkis opptrer også i magnetkisdominert malm (prøve .06). |
