The ephemeral fumarolic mineralization of the 2021 Tajogaite volcanic eruption (La Palma, Canary Islands, Spain)

The present work aims to characterize the ephemeral mineral assemblage related to the fumarolic fields of the Tajogaite volcano, formed in 2021 in La Palma Island (Canary Islands, Spain). A set of 73 samples was obtained after two sampling campaigns in different fumarole sectors of the studied area....

A set of 73 samples was obtained after two sampling campaigns in different fumarole sectors of the studied area. Mineralization related to these fumaroles formed efflorescent patches located at variable distance from the main volcanic craters. Distal patches are predominantly whitish, while in the vicinities they typically show yellowish to orange colours. Field observations also revealed that fumaroles usually occur in elevated topographic areas as well as over fractured and porous volcanic pyroclastic materials. The mineralogical and textural characterisation of the Tajogaite fumaroles unfolds a complex mineral assemblage, comprising cryptocrystalline phases related to low (< 200 °C) and medium temperature (200–400 °C) conditions. In Tajogaite, we propose a classification of three different fumarolic mineralization types: (1) fluorides and chlorides located in proximal fumarolic areas (~ 300–180 °C); (2) native sulphur associated with gypsum, mascagnite and salammoniac (~ 120–100 °C) and (3) sulphates and alkaline carbonates typically occurred in distal fumarolic areas (< 100 °C). Finally, we present a schematic model of the formation of Tajogaite fumarolic mineralization and their compositional evolution developed during the cooling of the volcanic system.This research was funded by the MAGEC-REEmounts project (ProID-20211010027) of the Canarian Agency for Research, Innovation and Information Society (ACIISI by its initials in Spanish) of the Canary Islands Government, the Museum of Natural Sciences (Museu de Ciències Naturals) of Barcelona and the Spanish Council for Scientific Research (CSIC by its initials in Spanish).We would like to thank Miguel Ángel Morcuende as Director of the Canary Islands Volcanic Emergency Plan (PEVOLCA) for allowing us access to the Tajogaite area during fieldwork. We also thank Gerard Lucena for his thorough work in the elaboration of polished thin sections and Steve Burns for language and grammar correction. Publication fees have been charged by the project ULPGC Excellence, funded by the Consejería de Economía, Conocimiento y Empleo del Gobierno de Canarias. Finally, we would like to highlight the extraordinary work carried out during the volcanic emergency by the PEVOLCA team, the scientific and steering committees and the security and emergency forces. Their action and cooperation were essential in ensuring the safety of all concerned during this 3-month volcanic eruption in La Palma.Nature Publishing GroupAgencia Canaria de Investigación, Innovación y Sociedad de la InformaciónConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2024202420232024info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/348784reponame:DIGITAL.CSIC.
