Boron-rich abyssal pegmatites in HP/HT rocks of the Moldanubian Zone of the Bohemian massif.

Boron-rich abyssal pegmatites occur in high-grade rocks in the Moldanubian Zone, Bohemian Massif. They typically occur in high-grade metamorphic rocks of upper amphibolite to granulite facies with HP metamorphic conditions ...

Reconstruction of the mid-Devonian HP-HT metamorphic event in the Bohemian Massif (European Variscan belt)

Mid-Devonian high-pressure (HP) and high-temperature (HT) metamorphism-metamorphic rocks with late Ediacaran to mid-Devonian protolith ages. Mid-Devonian HP eclogite-facies metamorphism was swiftly followe...

Variscan Metamorphism in Silesicum (Eastern Sudetes, Bohemian Massif)

Thermobarometric studies indicate pressures (up to 5-6 Kb) and temperatures (up to 660 °C) for Variscan metamorphism in the Silesicum. There is a lack of any HP rocks....

Metamorphic ages for HP/HT rock pebbles - evidence for high exhumation rates at the E margin of European Variscides.

Close ages of the formation of HP/HT granulite pebbles and their deposition in the Upper Visean conglomerates of the Drahany Uplands indicate high exhumation rate at the eastern margin of the Bohemian Massif in the end of the Variscan orogen...
