Estudio espectroscópico y DRX de afloramientos terrestres volcánicos en la isla de Tenerife como posibles análogos de la geología marciana

Abstract: RESUMENSe ha llevado a cabo una selección de varios afloramientos volcánicos en la Isla de Tenerife (La Caldera de las Cañadas, vulcanismo histórico y la zona del Malpaís de Güimar) como posibles análogos terrestres de Marte, considerando los procesos volcánicos ocurridos durante algunas de las etapas geológicas del planeta rojo. En la selección de las áreas de estudio se han tenido en cuenta la diversidad de procesos de alteración, que incluyen fenómenos como meteorización y alteración hidrotermal. Estos proc… Show more

“…The reference samples stem (1) from several fieldtrips to terrestrial analogues including Rio Tinto (Spain), Tenerife (Spain), Svalbard (Norway), Faroe Island, etc. (Lalla et al, 2016(Lalla et al, , 2015Sansano et al, 2015) or 2were synthetized in the laboratory (Sansano-Caramazana, 2015). The spectral Raman collection of the mineral phases has been obtained using standard Raman systems and the RLS simulator system, processed and analyzed using the protocols for the ExoMars mission (Hermosilla et al, 2012).…”

“…The other terrestrial pumice samples came from Güimar Valley in the southern part of the island. The selected sample belongs to a recent volcanic group eruption with a global age lower than ten thousand years (Lalla et al, 2015b). The outcrop where the samples were collected is constituted by a big cone, and it associated lava field that extends to the coast.…”

“…The outcrop where the samples were collected is constituted by a big cone, and it associated lava field that extends to the coast. A general description of the materials can be resumed as basaltic with other small basaltic enclaves, like an islet (Lalla et al, 2015b). The most remarkable of the area are the processes of hydrothermal, subaerial, submarine alteration and the interaction of ancient materials with the most recent volcanic fluids (Lalla et al, 2015b).…”

“…All these samples have fluorescent responses when excited with the laser. In addition, several fluorescent natural samples from Tenerife island (Spain), which is considered a Martian analog, were used for the algorithm validation.…”
