Recommended route.
Already in the vicinity of Cala Matzoc (point A), in the old fossilized dunes that exist on the coast, we find a blower, an orifice trhough which air escapes at pressure at moments of strong waves, developed in the quaternary calcarenites. The calcarenites are very porous rocks, with many holes between the particles that form it, which favor the phenomena of erosion and the formation of coastal cavities

Continuing the route, the path runs along the edge of a small cliff. It is here (point B) where we can observe that the degree of fracturing and cracking of the rocks of the Lower Cretaceous has increased and the rocks have a broad aspect. In addition they begin to appear intercalations of greenish and dark gray marls, finely laminated and inclusions of iron oxides. This increase in the degree alteration of Cretaceous materials seems to increase in the climb to the tower d’Albarca.

Cala Matzoc is one of the five beaches on the route developed at the end of a torrent. In this case, the torrent, with E-W orientation, is called Torrent d’en Matzoc and is born in the Font des Verger, in the mountains of Artà.
At the northern end of the cove, we can see a deposit of red silts with abundant rounded gravels. It is an alluvial deposit, formed by the sedimens transported by the stream in relatively recent times (Pleistocene). The sets of gravel correspond to moments of great energy that constrast with the sedimentation of the silts. If we look at the base of the deposit, we will see an erosive surface in which there are many fragments of the bedrock, again limestones from the Cretaceous.
