| Forekomsten ligger over skoggrensen langs vestsida av en fjellskråning 1-2 km nord for Magnillsæter. En bilvei fører fram til Magnillsæter. Nilsen (1978) har markert tre skjerp i området, men kun to av disse ble gjenfunnet under befaringen i 1998. Det er ikke kjent når det ble skjerpet i området. Sulfidmineraliseringen består av svak til sterk disseminasjon av magnetkis, dels semi-massive linser, i grovkornet granat- og amfibol-rik bergart som trolig representerer en jernformasjon. Den ligger i en sekvens med vekslende amfibolitt og glimmerskifer. Forekomsten har ingen økonomisk interesse. I hovedskjerpet, Magnillsæter I er det skutt ut et skjerp på 2x3 m på vestsida av en markert rygg. På toppen av denne er det blottet amfibolitt med foliasjon 312°/30°. Malmsona er ca. 1,5 m mektig og består av disseminert og semi-massiv magnetkis i granat-amfibol-kvarts bergart (prøve HE0143.01-.02). Foliasjonen i malmsona er 332°/25°. Både over og under denne finnes finkornet kvartsglimmerskifer med skifrighet 6°/35°. |

| Caledonian sulphide deposits and minor iron-formations from the southern Trondheim region, Norway. |

| 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. |

| Nær toppen av en liten rygg er det skutt ut noe masse på to steder kun 5 m fra hverandre. En 30-40 cm mektig sulfidsone er blottet i de små skjerpene. Den består av disseminert og semi-massiv magnetkis i granat-amfibol-kvarts bergart (prøve HE0143.03-.04). Spor av kobberkis finnes. Over sulfidsona ligger amfibolitt som dels er granatførende, mens hard kvartsglimmerskifer ligger under den. |
