Brief description

In the coastal cliffs of the Morenos area it is possible to observe a network of volcanic fissural conducts (dykes) of diverse nature, from basaltic to trachytic. These dykes exhibit various stages of magmatic rise related to the different phases of volcanic activity on the island. Some of them present prismatic disjunction. There are also lava flows and hyaloclastites formed undersea, and basaltic subaerial lava flows from the Middle Miocene. This assemblage is covered by much more recent yellowish orange aeolianitic deposits (Quaternary), in which layers of silty-clay brownish paleosols have developed. The presence of root casts in these aeolianites indicates the presence of an ancient vegetation cover, which has developed on these sands around thirty-thousand years ago. Fossils of terrestrial gastropods also occur, many of them representing endemic species already extinct.
