Project Description

It comprises one of the three large North-South sand outcrops, in the northeastern sector of Lanzarote. To the east, Mala village. organogen fine grain wind sand deposits that in some areas reach more than 22 m. This sand corresponds to fields of dunes from the Upper Pleistocene that expanded all over the northeastern coast of Lanzarote. The sand is slightly cemented by carbonate and they have structures of wind type crossed stratifications. The lava flows from the eruption of Las Calderetas in Guatiza subsequently covered this field of dunes. On the profile of the dune, different paleosols can be observed. They have been analysed and dated by several authors in order to study the paleo-climatic changes of the Quaternary. Almost at the top, there are inter-stratiphicated pyroclastic deposits of uncertain origin.
A geosite with a mainly sedimentological interest, followed by a secondary volcanological, geomorphological, paleontological and stratigraphic interest. This geosite has great paleo-climatic implications, and it especially represents the climate changes during the Quaternary. There is easy access to it, and good conditions to observe the quarries excavated to exploit the sand. Numerous relevant articles based on the research of said deposits have been published.
