This study presents a geophysical-geochemical integrated model of the thermochemical structure lithosphere and uppermost mantle along transect from Northern Tyrrhenian Sea to Pannonian Basin, crossing northern Apennines, Adriatic Sea, Dinarides fold-thrust belt. The objectives are image crustal thickness variations characterize different domains. In addition, we evaluate topographic response op...

Abstract This contribution provides insights into ocean-floor hydrothermal metamorphism of the fast-evolving Dinaridic Neotethys. Mineralogical, geochemical and Sr isotope data collected from altered ophiolites non-ophiolite basalts/andesites tuffs active continental margin are consistent with alteration trajectories that reflect host-rock composition. suggests fluxes were restricted within a s...

The Lut block in eastern Iran is a micro-continental block within the convergent orogen between the Arabian, Eurasian and Indian plates. Large areas of the north-central, eastern, and western Lut block are covered by volcanic rocks of Paleogene, Neogene and Quaternary age.  Peak volcanic activity took place in the north-central part of the Lut block during the Eocene, and then dramatically decr...

Abstract Late Cretaceous felsic and latest Cretaceous-Paleogene basaltic volcanic rocks are exposed throughout the Kyrenia Range, N Cyprus. Field mapping of key, well-exposed western range indicates that volcanics mainly crop out in southerly, frontal part range, separated from farther north by a thrust. New U-Pb zircon dating primary age c. 74.0?Ma (Late Campanian). The characterised evolved c...

U-Pb geochronology of zircon grains retrieved from magmatic rocks intruding the Jadar block terrane in central Balkans is used here to add new constraints on accretion processes and provenance crustal sources this potentially exotic block. Using an unorthodox approach, we analyzed zircons extracted products Cenozoic (Cer Boranja granitoid massifs) Triassic magmatism (Bobija andesitic tuff - Pie...
