Název v původním jazyce

Plumbotectonic aspects of polymetallic vein mineralization in Paleozoic sediments and Proterozoic basement of Moravia (Czech Republic)

Popis výsledku v původním jazyce

A regional isotopic study of Pb and S in hydrothermal galenas and U-Pb and S in potential source rocks was carried-out for part of Moravia, Czech Republic. Results suggest model Pb-ages as Early Carboniferous and Triassic-Jurassic, the latter associatedwith MVT-like deposits. U-Pb data and Pb isotope evolutionary curves indicate that Late Devonian and Early Carboniferous sediments, especially siliciclastics, are the general dominant contributor of Pb for galena mineralization developed in sedimentary rocks. Plumbotectonic mixing occurred, it is deduced, only between lower and upper crust (the latter involving Proterozoic basement containing heterogeneous radiogenic Pb), without any significant input from the mantle. Lead and sulfur have been mobilizedfrom the adjacent rocks during multiple hydrothermal events.
