Magnetic fabric in amphibolized eclogites and serpentinized ultramafites in the Marianske Lazne Complex (Bohemian Massif, Czech Republic): Product of exhumation-driven retrogression?

Popis výsledku v původním jazyce

The largest body of metabasic rocks in the Bohemian Massif, the Marianske Lazne Complex (MLC), represents an Early Paleozoic ophiolite complex, which experienced poly-metamorphic evolution with an early high-pressure amphibolite, followed by edogite andsubsequent amphibolite facies overprint. This study aims to investigate the fabric relationships among the rock bodies and to analyze the deformation-recrystallization history of the MLC using the anisotropy of magnetic susceptibility (AMS). Magnetic susceptibility of the MLC rocks varies according to the presence of para- and ferromagnetic minerals as well as according to the primary lithologies. In weakly magnetic rocks (K-m < 1 x 10(-3) [SI]), the main carrier of susceptibility is paramagnetic maficsilicates, amphibole and biotite in amphibolites, clinopyroxene and garnet in eclogites, olivine and serpentine minerals in serpentinized ultramafite, and amphibole in gabbro. In highly magnetic rocks (K-m >> 1 x 10(-3)), ferromagnetic mi
