The 2010 Eyjafjallajökull lasted 39 days and had 4 different phases, of which the first third (14–18 April 5–6 May) were most intense. Most this period was dominated by winds with a northerly component that carried tephra toward Europe, where it deposited in number locations sampled rain gauges or buckets, surface swabs, sticky‐tape samples air filtering. In UK, collected from each Phases 1–3 combined range latitudes spanning length country. modal grain size gauge 25 μ m, but largest grains...
The Tokaj Mts. volcanism occurred in a thinning continental lithosphere regime at the final stage of subduction process. Using high-precision zircon U-Pb dating, four major explosive eruption events were distinguished. Among them 13.1 Ma Sátoraljaújhely and 12.0 Szerencs eruptions could have yielded large amount volcanic material (possibly > 100 km3) they associated with caldera collapse as shown by several hundred-metre-thick pyroclastic deposits long (>100 km) runout flow case eruption....
Abstract Loess–paleosol outcrops were logged and dated to trace loess cover during the Pleistocene in a low-elevation mountainous area. The exposed successions maximum of 15 m thick stratigraphically fragmentary. Still, results suggest that was deposited all climatically suitable periods within limits dating methods (ca. 400 ka), probably also beyond this. Luminescence measurements provided numerical ages from ca. 18 ka 200 minimum up >267 ka. Loess accumulation active relatively mild MIS...
Repeated explosive eruptions of large volume silicic magmas during the early-to mid-Miocene resulted in pyroclastic deposits covering at least 50,000 km 2 Pannonian Basin.They form extended marker horizons and therefore these formations have a great stratigraphic importance.Lithostratigraphic characterization classification rocks go back for more than century been used widely geological mapping among other things.In this paper, we outline former stratigraphical schemes developed products...
Combined zircon U-Th-Pb and (U-Th)/He dating was applied to refine the eruption chronology of last 2 Myr for andesitic dacitic Pilişca volcano Ciomadul Volcanic Dome Complex (CVDC), youngest volcanic area Carpathian-Pannonian region, located in southernmost Harghita, eastern-central Europe. The proposed ages, which are supported also by crystallization much younger than previously determined K/Ar ages. By every known center CVDC, repose times between eruptive events were accurately...
We present a novel approach to use zircon as correlation tool well monitor for magma reservoir processes in silicic volcanic systems. Fingerprinting eruption products based on trace element content and U-Pb dates of offers promising, previously underestimated tephra perspective, particularly cases where the main minerals glass are altered. Using LA-ICP-MS analyses, rapid cost-effective method, this study presents concentration data more than 950 crystals from scattered occurrences early...
Ciomadul is the youngest volcano in eastern-central Europe. Although its last eruption occurred at ca. 30 ka, there are independent indications for a high-crystallinity magma reservoir persisting beneath until present. In order to further test hypothesis of long-lived melt presence and better constrain nature timescales associated with subvolcanic storage system, over 500 zircon U-Th U-Pb spot ages (crystal interiors outer surfaces) were interpreted from dacitic rocks most productive...
Abstract Extensive structural field observations and seismic interpretation allowed us to delineate 7 deformation phases in the study area for Cenozoic period. Phase D1 indicates NW–SE compression perpendicular extension Late Oligocene–early Eggenburgian it was responsible development of a wedge-shaped Paleogene sequence front north-westward propagating blind reverse faults. D2 is represented by E–W middle Eggenburgian–early Ottnangian. The resulted erosion suites on elevated highs. followed...
Abstract Two distinct Permian volcanic epochs were revealed in the Pannonian Basin (eastern Central Europe) by U–Pb zircon geochronology: an older one (~ 281 Ma, Cisuralian) ALCAPA Mega-unit (Central Transdanubia, Hungary) and a younger episode 267–260 Guadalupian) Tisza (Southern Transdanubia eastern Basin, Hungary). The former is represented dacitic subvolcanic rocks (dykes) lavas, while latter dominantly crystal-rich rhyolitic–rhyodacitic/dacitic ignimbrites subordinate...
The South Alpine–Dinaridic realm was affected by igneous activity in the Middle Triassic; marine carbonate platforms and adjacent basins contain highly variable intrusive-volcanic assemblages. We studied petrography determined zircon U–Pb ages of Triassic volcanic products Transdanubian Range. geochemical features thus geodynamic context magmatism are badly known, as rocks experienced chemical alteration. exact duration is also poorly constrained, geochronological data former studies were...
ABSTRACT Late Pleistocene tephras derived by large explosive volcanic eruptions are widespread in the Mediterranean and surrounding areas. They important isochronous markers stratigraphic sections therefore it is to constrain their sources. We report here tephrochronology results using multiple criteria characterize products of Ciomadul volcano eastern–central Europe. This dacitic had an eruption stage between 57 30 ka. The specific petrological character (ash texture, occurrence plagioclase...
