A small pebble beach with turquoise water between volcanic cliffs.



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.

[Na baía do Zimbralinho podem-se observar rochas das sequências vulcânicas submarinas, de natureza basáltica, contemporâneas da fase de pré-emersão da ilha.
Aqui, observam-se os melhores exemplares de lavas em almofada ou em rolo (pillow lavas), assim denominadas devido ao seu aspeto de secção sensivelmente esférica.
Estas lavas são representativas de erupções subaquáticas, neste caso submarinas.
É ainda possível observar, na descida para a baía, alteração do tipo esferoidal ou em bola, ocorre frequentemente em rochas de origem magmática, devido ação erosiva causada pela diferença de temperatura e em especial pela ação química da água.
É notória a presença de um filão mugearítico (rocha de origem magmática), numa das arribas e que se estende até ao Pico do Espigão, assim como um outro filão, de dimensão e com disjunção prismática bem desenvolvida.]
