HOW ARE THE EMPLACEMENT OF RARE-ELEMENT PEGMATITES, REGIONAL METAMORPHISM AND MAGMATISM INTERRELATED IN THE MOLDANUBIAN DOMAIN OF THE VARISCAN BOHEMIAN MASSIF, CZECH REPUBLIC?
Popis výsledku v původním jazyce
The Moldanubian domain of the Variscan Bohemian Massif is characterized by a large number of rare-element pegmatites, which are of possible economic importance. In order to investigate timing relationships between emplacements of Li-bearing rare-elementpegmatites and the tectonometamorphic and magmatic evolution of this domain, 10 in situ U?Pb dates of minerals of the columbite?tantalite group from eight rare-element pegmatites, belonging to different pegmatite fields, have been obtained by the LA?SF?ICP?MS technique. As in former studies, our results suggest that assimilation of common Pb is very limited, and diffusion of radiogenic Pb is of minimal importance in columbite. Two ages of emplacement have been obtained. An older episode at ~333 + 3 Ma follows closely the generalized melting event that occurred at the end of the Moravo?Moldanubian phase, during exhumation of high-pressure rocks.
