Abstract The Variscan orogeny was responsible for the formation of a significant volume of igneous basement throughout present-day Europe. Detailed understanding of these rocks has, however, been obfuscated by significant overprinting during younger

The pre-Alpine evolution of the Central Alpine basement is dominated by magmatic and metamorphic events that occurred during an Ordovician orogenic cycle (ca. 480-440 Ma) and the Variscan orogenic cycle (ca. 350-300 Ma). A detailed zircon U-Pb data a

Relics of the pre-Mesozoic geology are preserved in the five crystalline basement complexes of the External Massifs. Precambrian metamorphic units and Precambrian to Palaeozoic sediments, inter-layered with volcanics and ultramafic rocks, suffered in

Im Gebiet des Gruben- und des Aerlengletschers im Oberhasli (Zentrales Aarmassiv, Schweiz) ist ein praherzynischer Altkristallinkeil aufgeschlossen, der im N und S vom herzynischen Mittagfluhbzw. Zentralen Aaregranit begrenzt wird. Die Gesteine des z

Mn-rich members of the pyrosmalite-family [(Mn, Fe)8Si6O15(OH, Cl)10], friedelite and schallerite have been identified as rock-forming minerals together with caryopilite, in several metamorphosed carbonate Mn-deposits. The phase assemblages and miner

In the system CaSiO3-CaMnSi2O6-CaFeSi2O6 extensive miscibility gaps between pyroxenoids and clinopyroxenes are observed. The miscibility gap between Mn-bustamite and Mn-wollastonite has been determined experimentally by a hydrothermal technique betwe
