“…At pH < 3.8, thermal waters are chemically transparent to CO 2 , enabling research to trace this deep magmatic marker inside a degassing crater despite the intervening hydrothermal system. In contrast to CO 2 , H 2 S and SO 2 will be partly scrubbed by the hydrothermal system in the "steam-heated" water phase as a solute S-species (HSO 4 − -SO 4 2− thiosulphates, polythionates) or deposited as a solid (elemental S, anhydrite, gypsum, alunites) [10][11][12][13][14].…”

The Fangaia mud pool provides a “window” into the hydrothermal system underlying the degassing Solfatara crater, which is the most active volcanic centre inside the restless Campi Flegrei caldera, Southern Italy. The present study aimed at unravelling the degassing dynamics of CO2 and H2S flushing through the pH 1.2 steam-heated Fangaia mud pool, an ideal field laboratory as a proxy of an active crater lake. Our results from MultiGAS measurements above Fangaia’s surface show that H2S scrubbing, demonstrated by high CO2/H2S ratios, was most efficient in the portions of the basin affected by diffusive degassing. Convective bubbling degassing instead was the most effective mechanism to release gas in quantitative terms, with lower CO2/H2S ratios, similar to the Solfatara crater fumaroles, the high-T end member of the hydrothermal system. Unsurprisingly, total estimated CO2 and H2S fluxes from the small Fangaia pool (~184 m2 in June 2017) were at least two orders of magnitude lower (CO2 flux < 64 t/d, H2S flux < 0.5 t/d) than the total CO2 flux of the Campi Flegrei caldera (up to 3000 t/d for CO2), too low to affect the gas budget for the caldera, and hence volcano monitoring routines. Given the role of the rising gas as “sediment stirrer”, the physical and chemical processes behind gas migration through a mud pool are arguably the creating processes giving origin to Fangaia. Follow-up studies of this so far unique campaign will help to better understand the fast dynamics of this peculiar degassing feature.

“…In general, elements do not reach the equilibrium and maximum fractionation between mineral and fluid under non-equilibrium conditions, resulting in D-values that are closer to unity than at equilibrium. There are no experimentallydetermined D-values for gypsum, as far as we are aware, and the gypsum-fluid D-values reported by Inguaggiato et al (2020) for gypsum precipitated from vials containing Kawah Ijen lake waters represent bulk solids that include co-precipitated barite, Al-sulfates as well as a silicate (likely amorphous silica). The major element composition of these bulk solids, in particular their high Na and K contents (Table 3 of Inguaggiato et al, 2020), suggests that these co-precipitated phases contribute significantly to the bulk composition.…”

Gypsum Precipitating From Volcanic Effluent as an Archive of Volcanic Activity

Records of volcanic activity are a key resource in volcano monitoring and hazard mitigation. The time period for which such records are available and the level of detail vary widely among volcanic centers and there is, therefore, a need for supplementary sources of this information. Here, we use growth-zoned gypsum as a mineral archive of the activity of Kawah Ijen volcano in East-Java, Indonesia. Gypsum precipitates where water seeps from the crater lake and hydrothermal system, and it has formed a 100 m long cascading plateau. A 19 cm plateau cross-section was analysed for minor and trace elements using laser-ablation ICP-MS. Absolute ages were assigned to this transect based on 210Pb dating. This 210Pb age model was corrected for variations in the 210Pb0 resulting from fluctuations in the volcanic radon flux by using 84Kr/36Ar and 132Xe/36Ar. The age model indicates that the transect covers a period from 1919 ± 12 to 2008 ± 0.2. Gypsum-fluid partition coefficients (D) permit the gypsum compositions to be converted to the concentrations in the fluid from which each growth zone grew. The D-values also show the compatibility of the elements in the gypsum structure, and identify the LREE, Sr, Pb, Tl, Ni, Co, Cu, Zn, Cd, Sb, Th, and Mo as least susceptible to contamination from rock fragment and mineral inclusions, and therefore as most reliable elements of the gypsum record. Compositional variability in the timeseries correlates with known element behavior in the Kawah Ijen system and shows three element groups: the LREE, Sr, and Pb that represent rock-leaching; Cu, Zn, and Cd, which have previously been linked to immiscible sulfide destabilization in a deep-seated basalt; and Sb, Tl, and As which point to a contribution from the shallow system and evolved magma. Moreover, the gypsum record shows that episodes of unrest and quiescence have a distinct compositional signature in Kawah Ijen seepage fluids, and can be distinguished. Thus, we show that gypsum is a sensitive recorder of volcanic activity and can provide detailed information on the state of the magmatic-hydrothermal system in the past.

“…Previous studies have already identified that in the hyperacid crater lakes of Poás (Costa Rica) and Kawah Ijen (Indonesia), gypsum precipitation can be responsible for the fractionation of REE dissolved in waters (Inguaggiato et al, 2018;Inguaggiato et al, 2020a;van Hinsberg et al, 2020). The distribution coefficients of REE, calculated between the REE in gypsum precipitated in the laboratory from the lake water and the REE dissolved in the lake water of Poás and Kawah Ijen crater lakes, demonstrate that LREE are preferentially scavenged by gypsum with respect to the HREE.…”

“…Since hyperacid volcanic fluids are more aggressive with respect to near-neutral and alkaline fluids during water-rock interaction, a higher amount of rock-derived elements, including Rare Earth Elements (lanthanides + yttrium; REE), is leached and mobilized (Michard, 1989;Lewis et al, 1997;Takano et al, 2004;Varekamp et al, 2009;van Hinsberg et al, 2010;Peiffer et al, 2011;Hikov, 2015;Inguaggiato et al, 2015;Varekamp, 2015;Inguaggiato et al, 2017;van Hinsberg et al, 2017;Woitischek et al, 2017;Inguaggiato et al, 2018;Inguaggiato et al, 2020a;Inguaggiato et al, 2020b). The geochemical and economic importance of REE prompted to study them in a wide variety of environments, among which the fluids associated with volcanic areas, and especially volcanic crater lakes (Kikawada et al, 2004;Takano et al, 2004;Varekamp, 2015;van Hinsberg et al, 2017;Inguaggiato et al, 2018;Inguaggiato et al, 2020a;Inguaggiato et al, 2020b;van Hinsberg et al, 2020). Consequently to the increasing knowledge of the geochemical behavior of REE, it is possible to develop several applications using REE as geochemical tracers of fluid-rock interaction in active volcanic systems.…”

Decades of geochemical monitoring at active crater lakes worldwide have confirmed that variations in major elements and physico-chemical parameters are useful to detect changes in volcanic activity. However, it is still arduous to identify precursors of single phreatic eruptions. During the unrest phase of 2009–2016, at least 679 phreatic eruptions occurred at the hyperacid and hypersaline crater lake Laguna Caliente of Poás volcano (Costa Rica). In this study, we investigate the temporal variations of Rare Earth Elements (REE) dissolved in Laguna Caliente in order to 1) scrutinize if they can be used as a new geochemical tool to monitor changes of phreatic activity at hyperacid crater lakes and 2) identify the geochemical processes responsible for the variations of REE concentrations in the lake. The total concentration of REE varies from 950 to 2,773 μg kg−1. (La/Pr)N-local rock ratios range from 0.93 to 1.35, and Light REE over Heavy REE (LREE/HREE)N-local rock ratios vary from 0.71 to 0.95. These same parameters vary in relation to significant changes in phreatic activity; in particular, the (La/Pr)N-local rock ratio increases as phreatic activity increases, while that of (LREE/HREE)N-local rock decreases when phreatic activity increases. REE concentrations and their ratios were compared with the variations of major elements and physico-chemical parameters of the lake. Calcium versus (La/Pr)N-local rock and versus (LREE/HREE)N-local rock ratios show different trends compared to the other major elements (Na, K, Mg, Al, Fe, SO4, and Cl). Moreover, a higher loss of Ca (up to 2,835 ppm) in lake water was found with respect to the loss of Al, K, and Na. This loss of Ca is argued to be due to gypsum precipitation, a process corroborated by the mass balance calculation simulating the precipitation of gypsum and the contemporaneous removal of REE from the lake water. The observed relations between REE, changes in phreatic activity, and the parameters commonly used for the monitoring of hyperacid volcanic lakes encourage investigating more on the temporal and cause-effect relationship between REE dynamics and changes in phreatic activity at crater lake-bearing volcanoes.
