Abstract:
Ultramafic rocks and detrial serpentinites in the central and southern part of the allochthon in Scandinavia have been investigated. The ultramafic bodies consist mainly of peridotites and olivinites, which are more or less serpentinised. Dunites, serpentinites, soapstones, sagvandites, harzburgites, and cortlandites also occur. These ultramafites appear as parts of layered intrusions and as isolated tectonic lenses. The latter are focussed in the present paper; they compose the great majority (>90 %) of the ultramafic rocks in the Scandinavian Caledonides. This category of rocks is referred to here as solitary, primitive ultramafites; being entirely composed of ultramafic material of mantle-like composition. (...)
