Tertiary-Quaternary subduction processes and related magmatism in the Alpine-Mediterranean region

Kinematic reconstructions and magmatic evolution illuminating crustal and mantle dynamics of the eastern Mediterranean region since the late Cretaceous

“…Medium-K calc-alkaline magmatism with mostly intermediate composition (commonly called arcrelated magmatism) results from (1) partial melting of a hydrous mantle source metasomatized during the subduction of an oceanic lithosphere and (2) a subsequent episode of magma fractionation and crustal assimilation in the melting assimilation storage and homogenization (MASH) zone at the base of the crust [Gill, 1981;Hildreth and Moorbath, 1988;Harangi et al, 2006]. In the eastern Mediterranean region, this medium-K calc-alkaline magmatism is represented with the late Cretaceous Balkans-Pontides magmatic province (figures 8a-h) [Yılmaz et al, 1997; A C C E P T E D M A N U S C R I P T…”

“…In the back-arc region, the increased geothermal gradient due to lithospheric thinning and underlying asthenospheric flow allow for the partial melting of the lower crust and possibly of the lithospheric mantle, supplying the MASH zone. This lithospheric mantle is often highly metasomatized as a result of the subduction of both continental and oceanic materials [Hawkesworth et al, 1995;Harangi et al, 2006;Ersoy and Palmer, 2013]. These magmas then show a higher magmatic alkali content giving high-K calc-alkaline to shoshonitic compositions.…”

Neogene-Quaternary Volcanic forms in the Carpathian-Pannonian Region: a review

“…Volcanic and/or intrusive activity took place since 21 Ma till 0.1 Ma with a distinct migration in time from west to east ( Figure 2). Volcanic forms show diverse compositions that were generated in response to complex syn-and post-collisional tectonic processes [1,2] involving subduction with roll-back, collision, slab breakoff, delamination, strike-slip tectonics and block rotations of two microplates [4][5][6][7]. Major groups of calc-alkaline rock-types (felsic, intermediate and mafic varieties) have been distinguished and several minor alkalic types also pointed out, including K-alkalic, shoshonitic, ultrapotassic and Na-alkalic.…”

“…Reviews have been published treating the space/time evolution of volcanic activity [1,2], geotectonic evolution [3] and petrology and geodynamic setting of volcanic activity [4][5][6][7]. That is the reason that these subjects are covered only in the extent necessary for a proper understanding of volcanic form presentation.…”

Origin and evolution of Cenozoic magmatism of Sardinia (Italy). A combined isotopic (Sr–Nd–Pb–O–Hf–Os) and petrological view

“…During the Cenozoic, a widespread igneous activity developed in the Mediterranean area, mostly within the Alpine suture zone and partially along the older Variscan suture in central Europe (e.g., Duggen et al, 2005;Harangi et al, 2006;Lustrino and Wilson, 2007;Lustrino et al, 2011;Carminati et al, 2012, and references therein). Most of the volcanological, mineralogical and geochemical features observed in the various circum-Mediterranean igneous districts are well represented in the island of Sardinia, which is thus a key-locality for magmatic and geodynamic studies on the basis of several considerations:…”
