  1. 1. Late-orogenic, ductile shear zones and protolith ages in the Svecofennian domain, central Sweden

    Författare :Karin Högdahl; Carl Ehlers; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mineralogy; Petrology and Geochemistry; mineralogi; petrologi och geokemi;

    Sammanfattning : The timing of deformation along ductile shear zones in the Svecofennian Domain in central Sweden has generally been constrained by their relationship to magmatic and metamorphic events of known age. A better resolution for the timing of the deformation can be obtained by direct, radiometric dating of minerals which are constituents of the shear fabric. LÄS MER

    Sammanfattning : Field studies encounter several complicating factors not studied in the models. Examples are oblique convergence, heterogeneous materials and thermal softening by intruding magmas. LÄS MER
