“…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.…”

“…Some of those processes include gas-rock, gas-water, gasgas and gas-atmosphere interaction, condensation and sublimation of the gaseous phase, which play fundamental roles in the gaseous phase composition emitted to the surface, but also in the products associated, like composition and extension of the hydrothermal alteration zones, mineralogical assemblage related to fumarolic deposits, among others. Diverse works have been focused in a. to relate the fluids composition with its evolutive pattern (e.g., Giggenbach, 1991Giggenbach, , 1996Giggenbach, , 1997; b. composition of gaseous phase condensed (e.g., Taran et al, 1995); c. composition of fumarolic deposits and sublimates (e.g., Africano and Bernard, 2000); d. relation between gaseous phase-condensates composition and sublimate mineral assemblage (e.g., Taran et al, 2001;Zelenski et al, 2013); e. distribution and composition of hydrothermal alteration both direct and remote techniques (e.g., Mia and Fujimitsu, 2012), and f. the relations between fluids composition and composition-distribution of the hydrothermal alteration (e.g., Africano and Bernard, 2000;Scher, 2012). To relate adequately and precisely fluids and its products (e.g., fumarolic deposits, hydrothermal alteration) a detailed study based on fluid composition (gas and condensed phases composition), sublimated and condensed mineral assemblage, and hydrothermal alteration composition-distribution has to be carried out.…”

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 holocrystalline nature of these tuffisites precludes recovery and lithification by the processes that govern welding of other, glassy, volcanic rocks (i.e., healing via structural relaxation of melt fragments; e.g., Quane and Russell (2005)). Other potential processes include, for example, hot pressing (Olgaard and Fitz Gerald, 1993), solid-state diffusion (Venkatachari and Raj, 1986) and precipitation of minerals from fluids (Taran et al, 2001) as these fragmented materials are subject to significant pressures, elevated temperatures and circulating fluids while residing in the volcanic edifice. Indeed, hot pressing at magmatic temperatures has been shown to almost annihilate porosity in ceramics on the timescale of hours (Venkatachari and Raj, 1986;Wang et al, 2002).…”

Abstract. Tuffisites, the products of subsurface fragmentation, transport and deposition, are common in explosive volcanic environments. Their study provides direct insight to the mechanical processes operating within volcanic conduits. Here we document the influence of the presence of coherent tuffisite veins on the physical properties of andesitic rocks. We find that (1) compressive strength is unaffected by the presence and/or orientation of tuffisites, (2) permeability doubles when tuffisites are oriented favorably (at 45 • to the fluid flow direction), and (3) ultrasonic wave velocities show a continuous increase with depth, independent of vein presence and orientation. Although the influence of tuffisites on andesitic rock properties determined here is modest, we emphasize that the material tested represents the post-eruptive state of tuffisite. Thus, these results likely delineate the upper and lower boundaries of strength vs. permeability and porosity, respectively. Our evidence suggests that, via compaction and lithification, tuffisites may restore the strength of the volcanic host-rocks to that of their pre-tuffisite values.

“…However, the constant hydrogen isotopic composition of the gases does not suggest the new magma supply. For instance, the increase in D/H ratio was observed prior to the magmatic eruption of Colima volcano in 1998 by the input of new magma in a shallow magma chamber (Taran et al, 2001). The constant temperature of fumarolic gases during this period also contradicts the idea of new magma injection at the Kudriavy.…”

Decade-long study of degassing at Kudriavy volcano, Iturup, Kurile Islands (1990–1999): Gas temperature and composition variations, and occurrence of 1999 phreatic eruption

A high-temperature (up to 940• C) fumarolic activity at Kudriavy volcano had been studied during 1990-1999. The maximum gas temperatures of the fumaroles were measured in 1992 as 940• C, then gradually decreased with time and reached to 907• C in 1999. Gas composition of the high-temperature fumarole became enriched in H 2 O and depleted in other gas components, in particular in CO 2 . Hydrogen isotopic compositions of the high-temperature fumarolic gases were gradually depleted in deuterium. The gradual and continuous decrease in temperature and changes in gas composition observed during the last 10-year suggest that a magmatic melt have been degassing in a relatively steady-state manner from a single magma chamber. The detail investigations in 1998 and 1999 revealed short-term changes in gas composition characterized by sporadic increases in H 2 , CO 2 , and S total after intense precipitations. Small-scale eruptions occurred on October 7, 1999 at the summit. The ratios of major gas components (C/S, C/Cl, S/Cl, C/F, S/F, and Cl/F) significantly increased just prior to the eruption. The eruption at the Kudriavy volcano in 1999 was likely a phreatic eruption as a result of the intense precipitations after unusually long dry period. Meteoric water penetrated into the hot zone of volcano edifice and rapidly boiled causing the eruption.
