(2012). Open-system evolution of the Füzes-tó alkaline basaltic magma, western Pannonian Basin: Constraints from mineral textures and compositions. Lithos, 140, 25-37. AB - The crystal-rich alkaline basalt of the Fuzes-to scoria cone in the Bakony-Balaton Highland Volcanic Field, western Pannonian Basin, Hungary has a unique mineral assemblage reflecting a mixture of diverse crystals of various origins. The pheno- and microphenocrysts are represented by olivine with chromian spinet inclusions, clinopyroxene and plagioclase. The basalt contains abundant (20-40 vol.% on a vesicle-free basis) xenocrysts of olivine, orthopyroxene, colorless clinopyroxene and spinet derived from different regions of the subcontinental lithospheric mantle. Rare green clinopyroxene xenocrysts are also present. The basalt also includes numerous spinel peridotite xenoliths. In one of them we studied several silicate melt veins which contain fresh vesiculated glass, chromian spinels, clinopyroxenes and olivines. The glass has an evolved subalkaline composition (56.9-64.6 wt.% SiO2, 6.6-8.1 wt.% Na2O + K2O). Magmatic chromian spinels and clinopyroxenes in the host basalt and in the silicate melt veins of the peridotite xenolith show two compositionally distinct populations (group1 and group2). Group1 chromian spinels and clinopyroxenes both have low Cr contents (18-41 Cr# (100*Cr/ (Cr + Al)) and 0.01-0.86 wt.% Cr2O3, respectively) and occur predominantly in the host basalt. Group2 chromian spinels and clinopyroxenes have higher Cr contents (46-54 Cr# and 0.34-1.8 wt.% Cr2O3, respectively) and appear mainly in the silicate melt veins. In addition, compared to the group] clinopyroxenes, group2 clinopyroxenes have higher MgO and SiO2, and lower TiO2 and CaO contents. Based on our detailed mineral-scale study, group] spinels and clinopyroxenes represent the host alkaline basaltic magma (magma]), while group2 crystals could have been derived from another silicate magma (magma2) that is represented by the silicate melt veins in the studied peridotite xenolith. It is notable that group2 spinels are also present in some olivine phenocrysts, and scarce group1 spinels appear in the silicate melt veins as well. In some cases, group1 and group2 chromian spinels coexist within the same olivine phenocryst, and clinopyroxene zones that have group1 and group2 compositions compose parts of the same clinopyroxene crystal in the host basalt. On the basis of these observations, we infer interaction between magma1 and magma2. The occurrence and interaction of two distinct magma batches suggest a complex magma evolution for this otherwise simple, monogenetic volcano and imply that open-system processes operated during the evolution of the Fuzes-to alkaline basaltic magma. Our results demonstrate the importance of mineral textures and compositions for understanding the complexity of magma processes that can be manifested at small-scale basaltic volcanoes.

Most of this period was dominated by winds with a northerly component that carried tephra toward Europe, where it was deposited in a number of locations and was sampled by rain gauges or buckets, surface swabs, sticky-tape samples and air filtering. In the UK, tephra was collected from each of the Phases 1–3 with a combined range of latitudes spanning the length of the country. The modal grain size of tephra in the rain gauge samples was 25 μm, but the largest grains were 100 μm in diameter and highly vesicular. The mass loading was equivalent to 8–218 shards cm−2, which is comparable to tephra layers from much larger past eruptions. Falling tephra was collected on sticky tape in the English Midlands on 19, 20 and 21st April (Phase 2), and was dominated by aggregate clasts (mean diameter 85 μm, component grains <10 μm). SEM-EDS spectra for aggregate grains contained an extra peak for sulphur, when compared to control samples from the volcano, indicating that they were cemented by sulphur-rich minerals e.g. gypsum (CaSO4⋅H2O). Air quality monitoring stations did not record fluctuations in hourly PM10 concentrations outside the normal range of variability during the eruption, but there was a small increase in 24-hour running mean concentration from 21–24 April (Phase 2). Deposition of tephra from Phase 2 in the UK indicates that transport of tephra from Iceland is possible even for small eruption plumes given suitable wind conditions. The presence of relatively coarse grains adds uncertainty to concentration estimates from air quality sensors, which are most sensitive to grain sizes <10 μm. Elsewhere, tephra was collected from roofs and vehicles in the Faroe Islands (mean grain size 40 μm, but 100 μm common), from rainwater in Bergen in Norway (23–91 μm) and in air filters in Budapest, Hungary (2–6 μm). A map is presented summarizing these and other recently published examples of distal tephra deposition from the Eyjafjallajökull eruption. It demonstrates that most tephra deposited on mainland Europe was produced in the highly explosive Phase 1 and was carried there in 2–3 days.

Swath profiles can overcome this problem since the elevation values are considered not only along a line but along a swath. In a swath profile, the pixels are classified according to distance and statistical parameters (min, mean, max) of the classes are plotted against distance. The swath is usually a rectangular form but more irregular planforms are also possible. A special case is the "central swath", in which distance is calculated from a centre point. Besides some methodological development, this paper presents three case studies. In the first example, swath analysis is used to characterize the tilted surfaces found in the hilly landscape between the Ko{double acute}szeg Mts and the Rába river (in W Hungary and E Austria). Swath analysis also works for the more dissected western sections, thus proving the strength of this method. The second example discusses the Torockó (Trascǎu) Mts (in the eastern part of Apuseni Mts in Romania). Here, some water gaps and several wind gaps cross the karstic main ridge. Swath analysis helped to identify wind gaps not mentioned in previous publications and therefore it supports important data when outlining the drainage evolution of the area. Third, "central swath" profiles were used in order to numerically characterize the denudation of Central Andean volcanoes. The "ideal volcanic cone profile" is derived from the Parinacota volcano and this model enables comparisons to be made with older, more denuded volcanoes in order to quantify erosion volume.
