Colourful hydrovolcanism
by Stephanie Flude, Edinburgh University / SUERC, Edinburgh, United Kingdom
Different degrees of oxidation during hydrovolcanism, followed by varying erosion rates on Lanzarote produce brilliant colour contrasts in the partially eroded cinder cone at El Golfo. Algae in the lagoon add their own colour contrast, whilst volcanic bedding and different degrees of welding in the cliff create interesting patterns.
