Structural architecture releasing deep-sourced carbon dioxide diffuse degassing at the Caviahue – Copahue Volcanic Complex

The link between carbon dioxide diffuse degassing and its structural control was examined in the Caviahue – Copahue Volcanic Complex, over an area of approximately 10 km 2 that encompasses five hydrothermal sites, namely, Anfiteatro, Copahue town, Las Maquinitas I, Las Maquinitas II and Las Máquinas...

The comparison between diffuse degassing structures directions and faults directions suggests that there is a structural control on diffuse degassing. Diffuse CO 2 is released through an early extensional setting, and it is emitted through normal faults, strike-slip faults and through areas with higher structural damage, such as relay areas between fault segments and terminations of individual fault segments. © 2019 Elsevier B.V.
