Summary
edit| Description |
Français : Photographie prise par l'engin sous-marin Cyana au cours d'une plongée de la campagne Geocyatherm au large du Mexique. La zone photographiée est un lac de lave, à proximité de sources hydrothermales. La localisation du complexe volcanique aura un impact sur la forme de l'appareil qui se développe lors d'une éruption sous-marine : des coussins de basaltes (communément appelés pillow lavas) pouvant alterner avec des tufs et tuffites scoriacées (dorsales océaniques) ou des dômes ovoïdes (lorsque le degré d'acidité de la lave est plus élevé, par exemple dans le cas d'arcs insulaires). English: Photograph taken by the Cyana underwater vehicle during a dive of the Geocyatherm campaign off the coast of Mexico. The area photographed is a lava lake, near hydrothermal vents. The location of the volcanic complex will have an impact on the shape of the apparatus that develops during an underwater eruption: basalt cushions (commonly called pillow lavas) which can alternate with scoriaceous tuffs and tuffites (oceanic ridges) or ovoid domes (when the degree of acidity of the lava is higher, for example in the case of island arcs). |
