“…The silicatotal alkali diagram (Fig. 3) indicates a phonolite/trachyte composition and confirms the close chemical affinity between Valea cu Pietre tephra and other Campanian Ignimbrite/Y-5 (CI) occurrences in the Lower Danube (Fitzsimmons et al, 2013;Veres et al, 2013), vent proximal deposits (Civetta et al, 1997;Signorelli et al, 1999) or even more distal tephra locations (Pyle et al, 2006). (Civetta et al, 1997;Signorelli et al, 1999), distal tephra occurrences within Russian loess (Pyle et al, 2006), the fluvial/loess sequence at Caciulatesti in southern Romania , and the nearby Urluia sequence (Fitzsimmons et al, 2013) …”

“…A number of volcanic ash occurrences within Pleistocene loess and fluvial deposits in the Lower Danube region of Romania have recently been assigned to the Campanian Ignimbrite/Y5 (hereafter CI) tephra by glass chemical fingerprinting and OSL dating of adjacent material (Constantin et al, 2012;Veres et al, 2013;Fitzsimmons et al, 2013). The CI tephra, originating in the Phlegrean fields of southern Italy and dated by 40 Ar/ 39 Ar to 39.28 ± 0.11 ka (De Vivo et al, 2001) has been widely identified in lacustrine, marine, loess and cave sediments, extending across the eastern Mediterranean and eastern Europe to north Africa and the Russian Plain (Thunnel et al, 1978;Ton-That et al, 2001;Pyle et al, 2006;Anikovich et al, 2007).…”

Abstract:In this study we present luminescence investigations of four samples of loess bracketing the Campanian Ignimbrite/Y5 tephra at the Rasova-Valea cu Pietre site, on the eastern bank of the Danube River, southeastern Romania. Investigations involved SAR-OSL dating on aliquots of fine (4-11 μm) and medium-grained (63-90 μm) quartz, as well as single grain analyses on 125-180 μm quartz. Luminescence dating results coupled with glass-shard chemical fingerprinting assign the depositional age and origin of the ash layer to that of the Campanian Ignimbrite/Y5 tephra, dated elsewhere using 40 Ar/ 39 Ar to 39.28 ± 0.11 ka. Fine-grained (4-11 μm) quartz SAR-OSL analyses yielded ages of 44.4 ± 4.5 ka below the ash, and 41.4 ± 4.2 ka above the ash layer. Single grain analysis on coarse-grained quartz, however, demonstrates that coarse material from these samples exhibits low sensitivity and responds poorly to internal checks of the SAR protocol in comparison with the finer sediment. This observation highlights the need for more extensive investigations into the luminescence properties of quartz as well as into the origin of quartz contributions from different primary sources in the Lower Danube loess steppe.

The most recent, mainly explosive eruptions of Ciomadul, the youngest volcano in the Carpatho-Pannonian Region, have been constrained by detailed field volcanological studies, major element pumice glass geochemistry, luminescence and radiocarbon dating, and a critical evaluation of available geochronological data. These investigations were complemented by the first tephrostratigraphic studies of the lacustrine infill of Ciomadul's twin craters (St. Ana and Mohoş) that received tephra deposition during the last eruptions of the volcano. Our analysis shows that significant explosive activity, collectively called EPPA (Early Phreatomagmatic and Plinian Activity), started at Ciomadul in or around the present- and organic matter from lacustrine sediments recovered from both craters, the last of these phreatomagmatic eruptions-that draped the landscape toward the east and southeast of the volcano-occurred at ~29.6 ka BP, some 2,000 years later than the previously suggested last eruption of Ciomadul.

Difficulties in volume estimation of the CI deposits arise owing to the unknown depositional limits and correlation of the Plinian and ignimbrite/co-ignimbrite phases, particularly at distance.…”

Tephra deposits in the deep sea can survive undisturbed for long periods of time and, on regional scales, tend to be much better preserved than their subaerial counterparts. In this study, grain size distributions and thicknesses of tephra deposits from the Campanian Ignimbrite (CI) eruption (39 000 yr BP; magnitude c. 7.7) preserved in thirty-three deep sea cores are analysed to infer key eruption parameters. Distal deep sea tephra thickness data show an exponential decrease with distance from source. Such trends are difficult to identify in distal subaerial data owing to reworking and limited exposure. We find that tephra grain size distributions are much less affected by depositional environment than thickness, with trends that are consistent across distal subaerial, lacustrine and deep sea environments. The CI layer exhibits bimodal grain size distributions to distances of c. 1000 km, after which it becomes unimodal. Such trends can be related to different mechanisms of tephra transport in the atmosphere, whereby at proximal to medial distances the Plinian and co-ignimbrite phases produce distinct plumes. Within 150 and 900 km from source, Plinian tephra constitutes 40 + 5% of the deposit volume. Beyond this region where coarse particles are deposited, the plumes merge and fines derived largely from co-ignimbrite elutriation are spread in the atmosphere at velocities greater than the settling velocities of the particles.
