Geological Heritage of Porto Santo Island

 




Geological Heritage of Porto Santo Island

 
 
Porto Santo is characterised by its great and rich geological diversity, from the scientific, tourist and educational point of view, features that give this tourist destination a very peculiar geomorphology, displaying unique geological formations, such as the emblematic example of the Pico da Ana Ferreira.

The Porto Santo Geopark offers a set of places of geologic significance (geoplaces), of special scientific importance, rarity and beauty, representative of this island and its geological history.

From the geological point of view, the island of Porto Santo is formed by a set of volcanic complexes of distinct composition, in the Northeast and Southwest areas and by sedimentary rocks that occupy the Central area and the South coast.

It is a relatively flat island with some reliefs, the highest being the Pico do Facho, at 517 metres. The West-Central region presents a planed area, with sandy-limestone aeolian deposits, which separate the volcanic reliefs of the Western and Eastern part.
The southeast coast is low and sandy; the remaining coasts are relatively steep forming generally inaccessible cliffs, where you can observe a set of imposing veins.
