Abstract Exceptional magmatic events coincided with the largest mass extinctions throughout Earth’s history. Extensive degassing from organic-rich sediments intruded by magmas is a possible driver of catastrophic environmental changes, which triggered biotic crises. One represented Central Atlantic Magmatic Province, was synchronous end-Triassic extinction. Here, we show direct evidence for presence in basaltic methane, generated or remobilized host sedimentary sequence during emplacement...
The structural hydroxyl content of the nominally anhydrous minerals (olivine and pyroxenes) in upper mantle is among important attributes that influence physical chemical features mantle. In this study, we provide detailed Fourier-transform infrared (FTIR) data on 63 petrographically geochemically well-defined xenoliths from Nógrád-Gömör Volcanic Field (Pannonian Basin, Central Europe). These show extremely low average contents (~0, 31 185 ppm for olivine, orthopyroxene clinopyroxene,...
We present a new model for the formation of Plio-Pleistocene alkaline basalts in central part Carpathian-Pannonian region (CPR). Based on structural hydroxyl content clinopyroxene megacrysts, 'water' their host is 2.0–2.5 wt.%, typical island arc basalts. Likewise, source rich (290–660 ppm), akin to ocean This high could be result several subduction events from Mesozoic onwards (e.g. Penninic, Vardar and Magura oceans), which have transported significant amounts water back upper mantle, or...
Abstract Mantle xenoliths from the Styrian Basin Volcanic Field (Western Pannonian Basin, Austria) are mostly coarse granular amphibole‐bearing spinel lherzolites with microstructures attesting for extensive annealing. Olivine and pyroxene CPO (crystal‐preferred orientation) preserve nevertheless record of coeval deformation during a preannealing tectonic event. shows transitional symmetry [010]‐fiber to orthogonal type. In most samples olivine symmetry, [001] axes pyroxenes also dispersed...
Clinopyroxene-enriched upper mantle xenoliths classified as wehrlites are common (~20% of all xenoliths) in the central part Nógrád-Gömör Volcanic Field (NGVF), situated northern margin Pannonian Basin Hungary and southern Slovakia. In this study, we thoroughly investigated 12 wehrlite xenoliths, two from each wehrlite-bearing occurrence, to determine conditions their formation. Specific textural features, including clinopyroxene-rich patches an olivine-rich lithology, orthopyroxene remnants...
Abstract Large igneous provinces (LIPs) whose magma plumbing systems intersect sedimentary basins are linked to upheavals of Earth’s carbon and sulfur cycles thus climate life history. However, the underlying mechanistic links between these phenomena elusive. We address this knowledge gap through short time-scale petrological experiments (1200°C 150 MPa) that explore interaction basaltic melt carbonaceous shale (mudstone) using starting materials from Canadian High Arctic LIP Sverdrup Basin...
This study focuses on upper mantle xenoliths from Sabar-hill (Bakony-Balaton Highland Volcanic Field), a newly discovered locality of xenoliths, situated in the central Carpathian-Pannonian region (CPR). The investigated seven peridotite and one pyroxenite record two episodes geochemical evolution local subcontinental lithospheric mantle. moderately deformed Group I reveal modal contents (≥9 vol% orthopyroxene), major element characteristics (depletion Al2O3 CaO orthopyroxenes) trace...
Unio crassus and tumidus mussels were collected at four sampling sites in the Tisza River (Hungary) to investigate their applicability as sentinel species for biomonitoring of microplastic contamination. Since mussels, filter feeders, are able ingest particles only below a physically defined size, it was expected that role rivers is restricted small particles, including fibers or microfibers. This assumption confirmed by our results, detected dominant all 80 mussel samples investigated. The...
Information on seismic anisotropy in the Earth's mantle can be obtained from (1) shear-wave splitting analyses which allow to distinguish single or multi-layered and delay time of fast slow polarized wave indicate its thickness, (2) studying peridotites where properties inferred lattice preferred orientation deformed minerals. We provide a detailed map western part Carpathian-Pannonian region (CPR), an extensional basin recently experiencing tectonic inversion, using data. then compare...

A cemetery section comprising 35 burials was excavated at the site of Tiszakürt-Zsilke-tanya. The burial rites suggest that community who interred their dead here East European steppe origin, settled primarily east Tisza River. graves were poorly furnished; main chronological indicators are melon seed-shaped beads and two pairs earrings with big bead pendants. Based on these, can be dated between 640s 680s. archaeological analysis is complemented by an anthropological, archaeozoological,...
Incorporation of hydrogen as structural hydroxyl (commonly referred to water) in nominally anhydrous mantle minerals is known for the 'hydrolytic weakening' effect, which decreases strength and electrical resistivity rock. Recent models have provided means calculating rheological properties from geochemical data upper xenoliths. In Carpathian-Pannonian region, xenoliths can be found on surface at five locations, both marginal central regions basin system. this study we present a...
The Styrian Basin is located at the westernmost part of Carpathian-Pannonian region, in transition zone between Pannonian and Eastern Alps. lithospheric mantle beneath (SB) was sampled by Plio-Pleistocene alkali basalts, which brought xenoliths to surface. Mantle from SB are mostly coarse granular, amphibole-bearing spinel lherzolites with microstructures indicating extensive annealing. Three geochemical events were recorded xenoliths. initial, ancient partial melting event followed an old...
Abstract Amphiboles in the upper mantle (most frequently pargasitic composition) have recently gained attention due to their role water budget and potential control on rheology physical discontinuity of layers mantle. Although nominally anhydrous minerals are often analyzed with Fourier transform infrared (FTIR) spectroscopy, amphiboles, especially natural samples, only rarely focus such studies because complex structure variable composition. In xenoliths, amphibole occurs not interstitially...
