Silurian or Upper ordovician fossils at Guolasjav'ri Troms, Norway

Abstract

In August 1979, specimens of rugose and tabulate corals, crinoids and brachiopods (Fig. 1a) were recovered from meta-limestones in a belt extending 0–3.5 km north-west of Guolasjav'ri, a mountain lake south-east of Kåafjord, Troms, in Norway (Fig. 2, locality I). This is the first fauna to be recognised in this part of the Caledonian nappe sequence in Troms. The presence of corals proves that these metalimestones are not older than Middle Ordovician which imposes constraints on the correlation of this series with units in the Caledonides to the north and south and has an important bearing on the problematic relationship between the dominant Scandian phase (mid-Silurian1) of the Central Scandinavian Caledonides and the Finnmarkian phase (late Cambrian2) of northernmost Scandinavia.
