Contrasting Eoalpine P-T evolutions in the southern Koralpe, Eastern Alps

摘要: The Koralpe crystalline complex and the Plankogel unit represent two lithologically distinct units within region of southeastemmost Austroalpine basement. Eoalpine P-T evolution these is derived from new petrographical data. show markedly different evolutions during early stages event. rocks experienced eclogite facies conditions with minimum pressures in range 15–16 kbar temperatures excess 700°C. At same time resided a shallower environment at 10–11 less than 600°C. tectonic emplacement into its present position on top took place after event relatively shallow crustal level. After their juxtaposition were affected by common amphibolite metamorphic overprint. distinctly history later imply that major processes operative this part basement Cretaceous. Such may have involved subduction oceanic continental lithosphere which lead to significant shortening
