Resumen

Jurassic metasedimentary rocks of the Telekesoldal Nappe (Inner Western Carpathians) were sampled for metamorphic studies. The Telekesoldal Nappe represents a mélange-like accretionary complex consisting of black shales, sandstone turbidites and olisthostromes, deposited by gravity mass flows in a backarc (forearc?) basin. It was affected by ductile deformation and metamorphic alteration connected to the Middle Jurassic-Early Cretaceous subduction and obduction processes of the Neotethys Ocean. In the case of the 120-140 Ma very low-grade metamorphism – which is younger than the subduction-related blueschist facies metamorphism (Faryad and Henjes-Kunst, 1997) – the peak temperature was ca. 300-350 ºC, while the minimum pressure was ca. 2-2.5 kbar.
