Brief description
In Zimbralinho bay it is possible to observe basaltic lithologies from the submarine volcanic sequences that were contemporaneous to the island’s pre-emergence phase. In here, excellent examples of pillow lavas, dubbed like this because of their approximately spherical cross-section appearance, are observed. These lavas represent subaquatic eruptions, in this case undersea.
On the way down to the bay, it is also possible to see spheroidal weathering on these materials. It is evident the presence of mugearitic dyke that extends to the Espigão Peak, in one of the cliffs, as well as another dyke with a well-developed prismatic structure.
