Amethyst veins in sandstone

Prospecting on the cliffs by the sea became prohibited (forbidden to collect on the rock). Crozon became Armorica Regional Nature Park year 1990'. Monitored by coastal agents (with the drones)

The large escarpments of the site are shaped by erosion in areas where the Armorican sandstone strata were crushed by the establishment of faults around -300 million years ago. Quartz crystallizations result from the cooling of siliceous fluids injected at the same time into the spaces generated by fracturing.
