Intense magmatic degassing through the lake of Copahue volcano, 2013–2014

2015

Here we report on the first assessment of volatile fluxes from the hyperacid crater lake hosted within the summit crater of Copahue, a very active volcano on the Argentina-Chile border. Our observations were performed using a variety of in situ and remote sensing techniques during field campaigns in March 2013, when the crater hosted an active fumarole field, and in March 2014, when an acidic volcanic lake covered the fumarole field. In the latter campaign, we found that 566 to 1373 t d -1 of SO 2 were being emitted from the lake in a plume that appeared largely invisible. This, combined with our derived bulk plume composition, was converted into flux of other volcanic species (H 2 O ~ 1098…

Estudio Hidrogeoquimico De Las Áreas Termales Del Complejo Volcánico Copahue-Caviahue

2016

Hydrogeochemical study on Thermal areas of the Copahue-Caviahue Volcanic Complex The hydrothermal system hosted in the Copahue- Caviahue Volcanic Complex consists of different geothermal areas around the Copahue volcano, whose last eruptive cycle started on December 22 of 2012. This work presents new data from the samplings of November 2012 and march 2013 in Las Maquinas, Las Maquinitas, villa de Copahue and Chancho-Có areas. These acid-sulfate and steam heated waters, presented changes in their SO4-2 concentrations, especially in Las Maquinas and Las Maquinitas areas. Meanwhile, SO4-2/Cl- ratios presented a strong decrease in the samples from November 2012, regarding the samples from 2013.…

¿Una nueva vertiente en el Volcán Copahue?: El caso del río Colorado.

El volcán Copahue (37°51′08″S–71°10′03″O) ha sido uno de los más estudiados del cinturón volcánico Argentino-Chileno, desarrollándose numerosos trabajos desde el punto de vista geoquímico, y en particular abarcando el estudio de las aguas del sistema. Dichos trabajos se concentran en su mayoría en las nacientes del sistema volcánico hidrotermal (SVH) (Agusto et al, 2012). Sin embargo, existen varios afluentes que alimentan al rio Caviahue de los cuales no se tiene mayor información. El objetivo de este trabajo es dterminar el origen de uno de ellos, el río Colorado. Desde el flanco E del volcán emanan dos vertientes ácidas (pH 1-2,5) y calientes (35-45°C) que se unen para formar el río Agri…
