| En øst-vest orientert, 65 m lang, 1-4 m bred og 0.5 - 1.5 m dyp røskegrøft finnes i et flatt, overdekket område 2.5 km sør for Røstvangen gruve. I røskegrøfta finnes flere soner med massiv magnetkis som er minst 1 m mektige. De veksler med finkornet amfibolitt og kvarts-biotitt skifer. Bergartene er dels kraftig forvitret. Prøve .03 er fra den mektigste ( > 1 m bred), tilnærmet massive magnetkissona som også inneholder grovkornet, idiomorf pyritt og spor av kobberkis. Den ligger i rusten glimmerskifer. Prøve .02 er fra en 1 m mektig semi-massiv magnetkissone som ligger over finkornet amfibolitt, 15 m lengre øst. Sulfidsonene er orientert tilnærmet nord-sør med moderat fall mot øst. |

| 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. |

| En 15 m lang, øst-vest orientert røskegrøft finnes 55 m sørsørøst for Lykkejevangen. Bergartene som stikker fram i grøfta er sterkt forvitra, men både finkornet amfibolitt og glimmerskifer er påvist. De er orientert tilnærmet nord-sør med moderat fall mot øst og stryker øst for bergartene i Lykkjevangen. Sulfidmineralisering ble ikke påvist i fast fjell, men massiv magnetkis med korte strenger med kobberkis i en hodestor blokk er prøvetatt (prøve .01). |
