Origin of eclogite and garnet pyroxenite from the Moldanubian Zone of the Bohemian Massif, Czech Republic and its implication to other mafic layers embedded in orogenic peridotites

Original language description

The granulite terrane of the Czech part of the Gföhl unit includes numerous small bodies of mantle derived peridotite, some of which contain layers or lenses of eclogite and garnet pyroxenite. These eclogitic rocks have generally been considered to be high-pressure crystal cumulates formed in the upper mantle. We present new analyses of whole-rock major and trace element contents for three kynanite-quartz eclogite samples taken from the Nové Dvory garnet peridotite body. Integrating these data with previously published analyses from the literature on eclogitic rocks from this terrane, we demonstrate that magnesian group of eclogites, including these three new samples, were originally formed as cumulus gabbros, which were later transformed to eclogitesin the mantle. A gabbroic origin for some mafic layers (Type II) has been advocated for other orogenic peridotites, such as Beni Bousera (Morocco), Ronda (Spain), and Horoman (Japan).

Czech name

Původ eklogitů a granátických pyroxenitů moldanubické zóny Českého masivu, Česká republika a implikace na ostatní mafické vrstvy vmístěné v orogenních peridotitech

Czech description

Za použití různých petrologických a geochemických metod byl zkoumán původ granátických pyroxenitů, které se vyskytují jako vrstvy a čočky v eklogitech Českého masivu. Současně byla nalezena genetická příbuznost s ostatními orogenními peridotity.
