Brief description
Miradouro da Ponta do Rosto is a privileged site where one can identify the general shape of Madeira Island, a shield volcano. On the coastal cliffs, one can observe the old island's internal structure that formed during the first stage of fissural volcanic construction in subaerial environment, the Intermediate Volcanic Complex (VCM). Numerous vertical dykes related to an old volcanic rift zone in the east-west direction are visible. The dykes can be exposed from the embedded rock or in “cabo real” by differential marine erosion. The Pedra Furada Fault, one of the main tectonic incidents in Ponta de São Lourenço, is also of particular relevance at this site.
From a geomorphological point of view, the relationship between the coastline erosion and the main volcano-tectonic structures is evident.
Relevant notes
Visiting a site of geological interest is the sole responsibility of the user.
The user must take precautions when visiting the site, taking into account the conditions of the terrain, weather conditions and other hazards, so that they do not create situations that put themselves or others at risk.
The user must respect private property. Access to private areas requires prior authorization from the owners.
The user must respect natural heritage, keeping it intact. The impact of your actions should be minimal.
