1. Geography and geometry of pre-Caledonian western Baltica: U-Pb geochronology and Palaeomagnetism
Abstract : In an attempt to reconstruct the pre-Caledonian cratonic margin of Fennoscandia, U-Pb geochronological and geochemical investigations have been performed on allochthonous orthogneisses in the northern Swedish Caledonides. The crystalline basement of the nappes have also been examined to further constrain the continuation of various chronologically defined orogenic belts. READ MORE

4. Testing Tectonic Concepts in the Seve Nappe Complex, Jämtland, Sweden
Abstract : When continental plates collide, one of the involved continents is subducted beneath the other one. As a consequence, the lithosphere thickens along the convergent plate boundary and causes the formation of a mountain belt. READ MORE
