Brief description
Ponta do Garajau presents great geological diversity, of high scientific value, the most notable of which is the Garajau surtseyan cone. It is a tuff cone formed by ash and block deposits (yellowish) associated with hydrovolcanic activity, alternating with lapilli deposits and bombs (black to reddish) associated with strombolian subaerial activity stages. The cone was built on a coastal cliff previously cut out in a succession of basaltic spills in the Funchal Formation, Upper Volcanic Complex (CVS). At the site, there are also two lodes that will have fed the later stages of the eruption.
