“…This result shows that REE incorporation in gypsum decreases progressively from Nd to Lu, with La distribution coefficients that are mostly lower with respect to Ce, Pr, and Nd. Praseodymium often has the highest distribution coefficient and hence suggests preferential incorporation in the gypsum crystals during the precipitation process (Inguaggiato et al, 2018). Here, these previous findings (La/Pr) N-local rock and the (LREE/HREE) N-local rock ratios were considered to investigate the possible causes of temporal variations of REE in Poás crater lake water.…”

“…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.…”

Inguaggiato et al (2018) investigated the geochemical processes that affect the pattern of REE at Laguna Caliente (2006)(2007)(2008)(2009), the active hyperacid and hypersaline crater lake of Poás volcano in Costa Rica, the study object of this investigation. Mainly, water-rock interaction processes, congruent dissolution of the andesitic rocks and the precipitation of secondary minerals like gypsum, seem to control the amount of REE dissolved in crater lake water (Inguaggiato et al, 2018).…”

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.

Partition of Rare Earth Elements Between Sulfate Salts Formed by the Evaporation of Acid Mine Drainage

et al. 2021

View full text Add to dashboard Cite

Acid mine drainage (AMD) contains rare earth element (REE) concentrations several orders of magnitude higher than those of the rest of natural waters and could be a secondary source of REEs. In arid to semiarid climates with a long dry season, the precipitation of efflorescent sulfates constitutes a transient storage of REEs. The REE partition among the Al-Fe-Mg-Ca sulfates formed by the evaporation to dryness of six different AMDs was investigated by statistical methods and by selective dissolution. The chemical composition of the evaporitic salts showed that only three principal components (PCs) could explain more than 80% of the variability in the six samples analyzed. PC1 was associated with Ca and light REEs and interpreted as gypsum, whereas PC2 was associated with Y and heavy REEs, which were not clearly associated with a major sulfate. Finally, PC3 included Mg, Fe and several transition metals (Cu, Ni, Co, Mn and Zn) and was interpreted as Fe(II)-Mg sulfates. Selective dissolution of the salt mixtures with solutions saturated in the major sulfates revealed that the REEs were only retained in gypsum and were practically absent from the rest of the sulfates. The incorporation of REEs into gypsum decreased from Pr-Nd to La and Lu and was strictly ruled by the differences in their atomic radii and that of Ca in eight-fold coordination. However, gypsum concentrated less than 20% of the REE inventory (< 1% for Sc); the rest probably formed one or more unidentified trace minerals. This indicates that gypsum may not be an efficient way to concentrate REEs from AMD.
