Summary: INTRODUCTION
The Scandinavian Caledonides consist of a
stack of thrust sheets, which were amalgamated
and thrust toward the east-southeast mainly as a
result of Silurian-Devonian (Scandian) collision
between Baltica and Laurentia (Roberts and Gee,
1985). Tectonothermal events of Late Cambrian
Early Ordovician (Finnmarkian) and Middle
Ordovician (Taconic equivalent) age are also
recorded at certain structural levels (e.g.,
Andréasson, 1994).
In the Early Devonian, the hinterland parts of
the orogen were extended, in part because of
orogenic collapse, as is well established in
western Norway (reviewed by Andersen, 1998).
The Møre-Trøndelag Fault Complex (Fig. 1A)
played a major role in the Devonian scenario,
acting as a ductile sinistral shear zone in a
developing transtensional and/or transpressional
strain regime in the surrounding regions (e.g.,
