The fully cored, 2150-m-deep Szombathely-II (abbreviated as Szh-II) well was drilled at the western margin of the Hungarian Danube Basin. Beneath a circa 2-km-thick Neogene post-to syn-rift basin fill, the well not only reached the pre-rift Upper Austroalpine (UAA) basement with its slightly metamorphosed Paleozoic units but also the underlying gre...

The Styrian Basin, located in the transition zone between the Pannonian Basin and the Eastern Alps, is believed to have formed above a lithospheric wedge affected by subduction as strongly supported by geophysical data (Aradi et al., 2017; Qorbani et al., 2015). The Late Miocene-Pliocene alkali basalts sampled the subcontinental lithospheric mantle...

The Styrian Basin occupies a transitional zone between the Pannonian Basin and the Eastern Alps, and geophysical data strongly suggest its formation within a suprasubduction setting[1]. The subcontinental lithospheric mantle beneath the basin was sampled by the Late Miocene-Pliocene alkali basaltic volcanism carrying mantle xenoliths to the surface...

The Styrian Basin, located in the transition zone between the Pannonian Basin and the Eastern Alps, is thought to have formed above a lithospheric wedge affected by subduction. The Late Miocene-Pliocene alkali basalts sampled the subcontinental lithospheric mantle beneath the basin, bringing mantle xenoliths to the surface [1]. These xenoliths are...

The Styrian Basin, situated in the transition zone between the Pannonian Basin and the Eastern Alps, is believed to have formed above a lithospheric wedge, which have been affected by a subduction. The Late Miocene-Pliocene alkali basalts sampled the subcontinental lithospheric mantle beneath the area, bringing mantle xenoliths to the surface (e.g....

This paper presents the results from a geographic information systems (GIS) workflow, which was used to analyze the spatial distribution and temporal evolution of volcanoes in the Mio-Pleistocene monogenetic Bakony-Balaton Highland Volcanic Field (BBHVF), located in the Pannonian Basin, Hungary. Volcanism occurred during the tectonic inversion in a...

The Styrian Basin, representing a possible supra-subduction setting is situated in the westernmost unit of the Carpathian-Pannonian region, in the intermediary zone between the Pannonian Basin and the Eastern Alps1,2. The evolution of the Styrian Basin was influenced by the dynamics of the Carpathian-Pannonian region. The Plio-Pleistocene alkali ba...

The Styrian Basin, situated in the transition zone between the Pannonian Basin and the Eastern Alps, is believed to have formed in supra-subduction setting. The Plio-Pleistocene alkali basalts sampled the subcontinental lithospheric mantle beneath the basin, bringing mantle xenoliths to the surface1,2. This study focuses on modally metasomatized su...

In this study, we performed high resolution 3D Raman mapping on primary multiphase fluid inclusions from a granulite and an eclogite of the Cabo Orte-gal Complex (NW Spain), the latter representing a former subduction zone environment. Several microns-sized inclusions are great targets to test the advantages and limitations of 3D Raman mapping. We...

Fluid and mineral inclusions in metamorphic rocks allow the understanding of fluid-involved processes in subduction-zones providing essential contributions to the nature of geochemical processes and element cycling in present day subduction zones. In this work, we studied ultramafic granulite from the high-pressure (HP) and high-temperature (HT) me...

We carried out 3D Raman imaging on primary multiphase fluid inclusions (MFI), found in granulites and eclogites of the Cabo Ortegal Complex (NW Spain), the latter representing rocks from a former subduction zone. These several micrometer-sized MFI contain complex mineral assemblages of sheet silicates, carbonates and a residual fluid phase, therefo...

Deep fluids in subduction zones and high-grade metamorphic environments are commonly aqueous and carbonic and thus solute-rich in many cases. Once these fluids are trapped as inclusions by the host mineral (e.g., garnet), the post-entrapment cooling would facilitate crystallization of intergrowing solids, generally consisting of carbonates and sili...

Primary multiphase fluid inclusions (MFI) were studied in one eclogite and two granulites from the Cabo Ortegal Complex (COC, NW‐Spain) by means of Raman imaging, SEM‐EDS and FIB‐SEM. Complementary, secondary MFI in pyroxenites from COC were also investigated. MFI hosted in eclogite and granulites occur along growth zones or in 3D clusters in garne...

Subduction zone fluids play an essential role in large-scale transport processes between the down-going slab and the overlying upper mantle, inducing earthquakes and metasomatism. Fluid inclusions, trapped in high pressure rocks, originating from such environments, yield direct information on the nature and chemistry of these fluids. Here a descrip...

Tourmaline-rich pegmatitic orthogneisses, tourmalinites, kyanite–chlorite–muscovite schists and quartzites crosscut by subordinate quartz–tourmaline veins and layers were newly described from the Sopron area, Western Hungary. The orthogneisses mainly consist of quartz, plagioclase, tourmaline, garnet and white mica. In smaller amounts K-feldspar, b...

In the Pleistocene alluvium of the Danube, near the surface of the whole section along the river above Dunaujváros, some big (even more than 1 m in diameter) blocks were detected during fieldwork carried out in the area. These blocks are of wide-ranging compositon and shape, and are embedded irregularly in the varied compositional gravels. The main...
