Brief description
On this geosite it is possible to observe the oldest rocks exposed on Madeira Island, part of the Lower Volcanic Complex (CVI).
This set of outcrops, due to its integrity and representativeness, should be used as a reference when characterizing the Porto da Cruz Formation, defining its simple stratotype.
The lithological characteristics of these rocks allows this volcanic-stratigraphic formation to be correlated with a submarine volcanic stage, in which the Madeira shield volcano was about to emerge and to form an island.
