Project Description
This geosite is a clear example of the interference between the volcanic construction processes and the sedimentation of wind sands on the island of Lanzarote, which in this case has favoured the creation of convergent relief shapes, whose conic shape and pyroclastic materials on the surface, mainly lapilli, has caused for them to be interpreted as strombolian volcanic buildings without a crater. Recent studies, although ongoing, have shown that this type of morphologies really correspond with great fossil dunes in a sector of slope fault of the area bordering with the Jable sector. They were subsequently totally covered by the deposits of a close recent eruption. The power of the pyroclasts deposit and the type and size of the fragments that form it, decrease as we are further away from the assumed focus, that could be Montaña de Tamia.
This geosite has mainly a stratigraphic interest, and also volcanological, geomorphological, sedimentological and paleontological. This is the only known examples of this type of convergence of shapes in the Canarian archipelago. There are good observation conditions due to the mining activity of the volcanic charcoal.
