Dataset of particle size distribution data of Holocene volcanic ashes of NW Argentina
No full textGrain size distributions were determined in volcanic ash samples using a Malvern Mastersizer 2000 particle analyser, equipped with a laser diffractometer (ultrasonic water disaggregation: Hydro MU system; absorption: 0.1; refractive index: 1.52; measurement time: 20 s; obscuration: 10–20%; and pump speed: 2500 rpm, 3 measures), following the recommended procedures of the International Volcanic Health Hazard Network (IVHHN, www.ivhhn.org). This technique measures particles of 0.1–1000 μm using the Mie Theory; due to this limitation, only distal ash samples with maximum grain sizes of < 1 mm for the complete deposit (not grain fractionated) were analysed. The particle-size abundance is reported as the volume percentage of equivalent spherical diameter. Contact person: Fernandez-Turiel, J. L., [email protected] dataset includes particle size distribution data of volcanic ashes of Southern Puna and neighbouring areas (NW Argentina). The content of particles of 0.1–1000 μm was determined by lasser diffraction. The studied volcanic materials are mainly associated with the 4.2 ka cal BP eruption of the Cerro Blanco Volcanic Complex. Some samples area related to the Cueros de Purulla volcano.MINECO, CGL2011–23307N

Estudios Geológicos 75(1): e088. https://doi.org/10.3989/egeol.43438.515This dataset compiles SEM images, modelled isopach map and topographic profiles, and data of radiocarbon ages, parameters of Tephra2 and AshCalc codes of Holocene volcanic ashes of of Southern Puna and neighbouring areas (NW Argentina). SEM images detail differences among the Bolsón de Fiambalá, Cerro Blanco and Cueros de Purulla fallout ash deposits. Tephra2 code was used to simulate the ash fallout, and the AshCalc code to compare different methods for ash volume estimates associated with the 4.2 ka cal BP eruption of the Cerro Blanco Volcanic Complex. Topographic profiles are used to explain the secondary thickening of fallout ash deposits.MINECO, CGL2011-23307, Proyecto QUECAPeer reviewe

Dataset of glass and mineral geochemical data of Holocene volcanic ashes of NW Argentina
No full textAnalytical results were determined by a CAMECA SX-50 and a JEOL JXA-8230 electron probe microanalysers (EPMA) at the EPMA Laboratory of the CCiT services of the University of Barcelona. The instruments were calibrated using primary natural and synthetic standards. The quality of mineral analyses was reviewed, verifying that the structural formula gave a correct stoichiometry, with specific measuring programs for feldspars, biotite, Fe–Ti oxides, pyroxene, and amphibole.Contact person: Fernandez-Turiel, J. L., [email protected] glass, phenocrysts, microphenocrysts, and microlites of glass shards (1011 analyses at single points), feldspars (568), biotites (183), Fe–Ti oxides (101), amphiboles (30), and pyroxenes (14) were analysed on polished thin sections of Holocene volcanic ashes, ignimbrites and lava domes of Southern Puna and neighbouring areas (NW Argentina) by electron probe microanalyser (EPMA). The quality of mineral analyses was reviewed, verifying that the structural formula gave a correct stoichiometry with specific measuring programs for feldspars, biotite, Fe–Ti oxides, pyroxene, and amphibole. Geothermobarometry was constrained using the chemistry of feldspars, Fe–Ti oxides, clinopyroxene, and amphibole.

Dataset of total and nitric acid soluble element concentrations from stream sediments of the Upper Garonne Basin, Val d'Aran, Central Pyrenees
No full text1) For whole rock: sieved <180 µm size fraction, pulverized in a vibrating cup laboratory mill, 0.1 g sample digested in HNO3:HClO4:HF (2.5:2.5:5.0, v/v), doubly evaporated to incipient dryness, addition 1 mL HNO3, and made up to 100 mL with Milli-Q Plus ultrapure water type (18.2 MΩ/cm) ; 2) For nitric acid leaching: 0.1 g sample mixed with 1 mL de HNO3 in 12×100-mm polypropylene test tubes In batch experiments, and made up to 100 mL with Milli-Q Plus ultrapure water type (18.2 MΩ/cm). Final solutions were analysed by HR-ICP-MS. Contact person: Fernandez-Turiel, J. L., [email protected] dataset comprises the total and the acid nitric soluble element concentrations of major and trace elements (Si, Ti, Al, Fe, Mn, Mg, Ca, Na, K, P, LOI, As, Ba, Be, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Ga, Gd, Ge, Hf, Ho, La, Li, Lu, Mo, Nd, Ni, Pb, Pr, Rb, Sb, Sc, Sm, Sn, Sr, Tb, Th, Tm, U, V, Y, Yb, Zn, Zr) in stream sediments of the Garonne River watershed in the Val d'Aran in the Central Pyrenees. We used samples collected in 1981 in a pilot project of stream sediment geochemistry. The results of nitric acid leachates are used as proxies of the environmentally available fraction of such elements. The samples represents the lithogeochemical units consisting of the Maladeta-Marimanya granitoids, and the metasediments occurring in an extensive area of the basin.Peer reviewe

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
