A symposis is given of 4-5 weeks of field work in the Sylene area, Sør-Trøndelag, Norway, in the eastern part of the Cambro-Silurian geosyncline of Trondhjemsfeltet. Previous investigations are reffered to. The rocks in the area are mainly sedimentary or volcanic, lying with their strike approximately N-S, and the stratigraphically lower units in the east. The rocks as they appear from east to west in the field: a) arkoses, lower border not investigated, b) hornblende-garbenschist, c) Stuedalschist (mica-schist with biotite porphyroblasts inclined to schistosity plane), d) greenschist, e) alternation of greenschist\/dark micaschist with single sandy horizons, f) coarse, quartz-rich schists, with trondhjemitic layers or sills, g) greenschist, with trondhjemitic layers or sills.
