“…In the case of alkali metals, its behaviour can be considered "normal", with decreasing of log EF i as follow Cs>Rb>K>Na, except in Last_Cond_1 where Rb>Cs. This order follows the principle that the volatilities of the elements increase with increasing atomic number in a group (Zelenski et al, 2014). Three elements present the highest log EF i values in both samples, corresponding to iodine, chlorine and bromine, with log EF i >5 (Fig.…”

“…However, elements normally derived from the host rock, like REE and some alkali earth metals as Sr, show log EF i values over 2 (Fig. 7a, b), a contrary behaviour as observed in other arc-related volcanoes (Taran et al, 1995(Taran et al, , 2001Zelenski et al, 2014). The higher enrichment of those elements in LVC condensates could be related to the incorporation of hydrothermal fluids in the high temperature fumaroles.…”

ABSTRACT.A multidisciplinary study that includes processing of Landsat ETM+ satellite images, chemistry of gas condensed, mineralogy and chemistry of fumarolic deposits, and fluid inclusion data from native sulphur deposits, has been carried out in the Lastarria Volcanic Complex (LVC) with the objective to determine the distribution and characteristics of hydrothermal alteration zones and to establish the relations between gas chemistry and fumarolic deposits. Satellite image processing shows the presence of four hydrothermal alteration zones, characterized by a mineral assemblage constituted mainly by clay minerals, alunite, iron oxides, and more subordinated ferrous minerals and goethite. Hydrothermal alteration zones present in the Lastarria sensu stricto volcano are directly related to the recent fumarolic activity. Geochemistry of fumarolic gas condensed, obtained from two fumaroles at temperatures between 328 and 320 °C, has allowed detecting 37 diverse elements corresponding to halogens, chalcophiles, siderophiles, alkali metals, alkali earth metals and Rare Earth Elements (REE), with concentrations that vary widely between 5,620 ppm (chlorine) and 0.01 ppm (Mo, Ag, Sn, Pb, Se, Mg and Cr). Logarithm of Enrichment Factor (log EF i ) for each element present values between 6.35 (iodine) and <1 (K, Na, Ca, Fe and Al). Those elements are originated primarily from a magmatic source, whereas at shallow level a hydrothermal source contributes typical rock-related elements, which are leached from the wall rock by a strong interaction with hyperacid fluids. Mostly of elements detected are transported to the surface in the fumarolic emissions as gaseous species, while very few elements (Mg, Ca and Al) are transported in silicate aerosols. A wide spectrum of minerals are present in the fumarolic deposits, which are constituted by sublimates and incrustations, and the main minerals phases are distributed in six mineral families, corresponding to sulphates, hydrated sulphates, sulphides, halides, carbonates, silicates and native element minerals. The sublimate/incrustation minerals are dominated by the presence of sulphate, sulphur, chlorine and diverse rock-related elements, which are formed by processes that include a. oxidation of gaseous phase; b. strong rock-fluid interaction; c. dissolution of silicate minerals and volcanic glass; d. gas-water interaction; e. deposition/precipitation of saline bearing minerals; f. oxidation of sublimates/incrustations to form secondary minerals and g. remobilization of sulphur deposits by meteoric water. Despite that sublimate/ incrustation minerals are dominated by rock-related elements, its chemistry shows high contents of high-volatile elements as As, Sb, Cd, among others. Fluid inclusions studies carried out in thin pseudobanded native sulphur from fumarolic deposits, by use of Raman and infrared spectroscopy combined with microthermometry analyses, provided evidence of H 2 O, CO 2 , H 2 S, SO 4 , COS bearing fluids, homogenization temperatures around 110 °C and salinities v...

“…The eruption produced three large lava fields extending up to 17.8 km (Dvigalo et al, 2014); effusion ceased in early September 2013. The first results of various scientific studies have been published by several authors (Samoylenko et al, 2012;Saltykov et al, 2012;Edwards et al, 2013;Gordeev et al, 2013b;Volynets et al, 2013;Dvigalo et al, 2014;Ermakov et al, 2014;Fedotov et al, 2014;Zelenski et al, 2014).…”

“…The last three major Tolbachik eruptions occurred in 1941, 1975-1976, and 2012-2013, and occurred along the SSW "rift" zone. The total volume of ejected lava and tephra during these three eruptions was approximately 2.0 km 3 dense rock equivalent (DRE), a volume recalculated to a density of 2.8 g/cm 3 for nonvesiculated magma taken from the average densities of slightly vesicular lavas of 2.5 g/cm 3 and pyroclast densities of 1.1 g/cm 3 , which corresponds to an average rate of lava production of 0.86 m 3 /s for the last 72 years (Polyak and Melekestsev, 1981;Zelenski et al, 2014). According to this production, Pl.…”
