Anse Saint-Martin
During certain high tides, an ancient peat bog with its fossil tree trunks can be observed on the current foreshore of Anse St Martin. This appearance suggests the submersion by the sea of a marsh larger than the current one.
A legend describes the submersion of a forest and the destruction of the "Old Church" following the opening of a breach in the coastal barrier during a storm. It is said to have originated in an event dating back to the 7th century AD, which would coincide with the end of the peat sedimentation actually observed on the foreshore. A disturbing coincidence.
The current marsh of Anse St Martin, located behind the pebble strip, persists due to the high level of freshwater tables in the coastal plain.
The study of all the sedimentary formations of Anse has made it possible to reconstruct the living environment of human populations and their use of the environment since the Middle Paleolithic.
Monzonite from Anse Saint-Martin
A rock named after this cove is "the Monzonite of Anse St Martin." It has the particularity of hosting dark enclaves which correspond to pieces of magma from the melting of the mantle brought up with its own magma. This rock is dated 580 Ma and is a witness to Cadomian history.
