From Cilheta to Tonel walking between millions of years
In a walk between the beaches of Cilheta and Tonel it is possible to observe the nature of the border between the Middle Jurassic (175 - 161 million years) and the Upper Jurassic (161 - 145 million years).
The activity consists on a walk between Cilheta and Tonel beach. Along the way we can observe layers of limestones and marls with various geological and fossil structures. In the transition between these two beaches, the boundary between the limestone layers of the Middle Jurassic (Cilheta) and the layers of the Upper Jurassic (Tonel) is observed. This border corresponds to a unconformity in the stratigraphic record, suggesting that before the deposition of the layers of the Upper Jurassic the layers of the Middle Jurassic were deformed and eroded.
