“…Magmatic activity postdates Middle Miocene subduction (Cloetingh et al 2004) and is thus considered to be postcollisional (Mason et al 1998;Seghedi et al 1998Seghedi et al , 2019. CGH magmatism is characterised by a clear south-eastward decrease in age and intensity (Peltz et al 1987;Pécskay et al 1995Pécskay et al , 2006Szakács et al 1997Szakács et al , 2018 and produced adjoining composite volcanoes and peripheral volcaniclastic aprons (Szakács and Seghedi 1995), with products ranging from basalts to rhyolites (Seghedi et al 1995;Mason et al 1996).…”

“…Calc-alkaline magmatism ensued in a 160-km long volcanic chain, termed Călimani-Gurghiu-Harghita (CGH), with minor eruptions of alkaline and potassium-rich magmas at the southern end (Perșani and Southern Harghita, respectively; Rădulescu and Săndulescu 1973;. Magmatic activity gradually shifted from northwest (~ 10 Ma) to southeast (< 0.03 Ma) with waning intensity (Peltz et al 1987;Pécskay et al 1995Pécskay et al , 2006Szakács et al 1997Szakács et al , 2018, and has been linked to progressive along-strike slab breakoff (Mason et al 1998;Seghedi et al 1998) and/or lithospheric removal (e.g. Houseman and Gemmer 2007).…”

The occurrence of post-subduction magmatism in continental collision zones is a ubiquitous feature of plate tectonics, but its relation with geodynamic processes remains enigmatic. The nature of mantle sources in these settings, and their interaction with subduction-related components, are difficult to constrain using bulk rocks when magmas are subject to mixing and assimilation within the crust. Here we examine post-collisional magma sources in space and time through the chemistry of olivine-hosted melt inclusions and early-formed minerals (spinel, olivine and clinopyroxene) in primitive volcanic rocks from the Neogene-Quaternary East Carpathian volcanic range in Călimani (calc-alkaline; 10.1-6.7 Ma), Southern Harghita (calc-alkaline to shoshonitic; 5.3-0.03 Ma) and the Perșani Mountains (alkali basaltic; 1.2-0.6 Ma). Călimani calc-alkaline parental magma compositions indicate a lithospheric mantle source metasomatised by ~ 2% sediment-derived melts, and are best reproduced by ~ 2-12% melting. Mafic K-alkaline melts in Southern Harghita originate from a melt-and fluidmetasomatised lithospheric mantle source containing amphibole (± phlogopite), by ~ 5% melting. Intraplate Na-alkaline basalts from Racoș (Perșani) reflect small-degree (1-2%) asthenosphere-derived parental melts which experienced minor interaction with metasomatic components in the lithosphere. An important feature of the East Carpathian post-collisional volcanism is that the lithospheric source regions are located in the lower plate (distal Europe-Moesia), rather than the overriding plate (Tisza-Dacia). The volcanism appears to have been caused by (1) asthenospheric uprise following slab sinking and possibly south-eastward propagating delamination and breakoff, which induced melting of the subduction-modified lithospheric mantle (Călimani to Southern Harghita); and (2) decompression melting as a consequence of minor asthenospheric upwelling (Perșani).

“…With coordinated and systematic observations of the recent satellite mission Sentinel-1 of the ESA Copernicus Earth observation mission new research avenues are foreseen in the detection of small-scale surface deformations. Szakács et al (2018) (in this issue) presents a geochronological and geochemical review of the Neogene volcanic activity of the Carpathian-Pannonian region. This study reviews how these data could outline the geodynamic processes acting at the origin of magmatic activity and how these observations maybe reconciled in the light of deep and surface processes.…”

“…Complex post-collisional (sensu Seghedi and Downes 2011) tectonic processes in the CPR generated, together with evolution of magmas in the crustal environment, a Lower Miocene to recent magmatic events with products of highly diverse composition. Overall, CPR magmatic activity shows a distinct migration in time from west to east (Pécskay et al 2006;Harangi and Lenkey 2007;Seghedi and Downes 2011;Lukács et al 2015Lukács et al , 2018Szakács et al 2018).…”

Mts. Kalnik and Požeška gora volcaniclastic sequences hold valuable information concerning the Miocene syn-rift evolution of the North Croatian Basin, and the evolution of the Carpathian-Pannonian Region and the Central Paratethys. We present volcanological, high-precision geochronological, and compositional data of volcanic glass to constrain their tephrochronology, magmatic provenance, and timing of the initial Central Paratethys flooding of the North Croatian Basin. Based on CA-ID-TIMS U-Pb zircon ages (18.060 ± 0.023 Ma for Mt. Kalnik and 15.345 ± 0.020 Ma for Mt. Požeška gora) and coeval 40 Ar/ 39 Ar sanidine ages (18.14 ± 0.38 Ma and 18.25 ± 0.38 Ma for Mt. Kalnik and 15.34 ± 0.32 Ma and 15.43 ± 0.32 Ma for Mt. Požeška gora), Mt. Kalnik rhyolitic massive ignimbrites and Mt. Požeška gora rhyolitic primary volcaniclastic turbidites are coeval with Carpathian-Pannonian Region Miocene post-collisional silicic volcanism, which was caused by lithospheric thinning of the Pannonian Basin. Their affiliation to Carpathian-Pannonian Region magmatic activity is supported by their subduction-related geochemical signatures. Although Mts. Kalnik and Požeška gora volcaniclastics are coeval with the Bükkalja Volcanic Field Csv-2 rhyolitic ignimbrites, North Alpine Foreland Basin, Styrian Basin, Vienna Basin, and Dinaride Lake System bentonites and volcaniclastic deposits, reliable tephrochronological interpretations based on comparison of volcanic glass geochemical composition are not possible due to a lack of data and/or methodological discrepancies. Our new high-precision geochronology data prove that the initial Middle Miocene (Badenian) marine flooding of parts of the North Croatian Basin occurred at least ~ 0.35 Ma (during the NN4 Zone) before the generally accepted ~ 15 Ma maximum flooding age at the basin scale, calibrating the timing of the onset of the widespread "mid-Langhian" Central Paratethys flooding.
