Solitary mantle peridotite bodies in Stølsheimen, Central South Norway.

The peridotite bodies in Stølsheimen are located in the mélange unit 
which consist of metapelites. The peridotite bearing mélange unit is 
situated between the upper and lower Bergdals nappe in Stølsheimen  
Recent work suggest that such solitary "Alpine-type" peridotites may be 
occasionally exhumed to the surface during extreme extension of the 
crust in passive continental margins.

Two peridotite bodies (Raudberget and Vetle Raudberget) have been mapped 
in detail and geochemical analyses have been carried out. The data from 
the two peridotite bodies have been compared with data from similar 
rocks from other parts of the Caledonides and other orogenic belts.
