Jersey Offshore Reefs

Jersey is surrounded by offshore reefs bursting with marine life, Les Pierres de Lecq to the north, Les Écréhous to the northeast and Les Minquiers to the south. Local fisherman enjoy fishing around these reefs which often prove dangerous to larger ships. There are over 400 shipwrecks around the Island.

Geology

Rozel Conglomerate

The Rozel Conglomerate Formation can be seen along the northeast of the Island and is made up of beds of pebbles which have been cemented together.

Jersey Granites

Geology

Jersey Shale Formation

The shales are the oldest rocks in the Island. You can see them in the west, across the centre and in the south of Jersey. They were formed by mud, silt and sand brought together on the sea floor about 600 million years ago. These sediments were transformed into rock by being pushed together, hardened and folded.
