Geology Fieldwork – Rinsey Cove

The granite here forms the headlands either side of Rinsey Cove and Mylor Slate formation dips down into the top of the granite forming a roof pendant. The softer slate has been eroded away to form the cove and the contacts with the granite are exposed on either side of the sandy beach.

The dykes and sills emanating from the granite into the slate show how granite is emplaced into the country rock by the process of stoping. The different angles of contact exposed on the wave-cut platforms provide a great introduction to the principles of geological mapping.

An ideal site for mapping a granite contact at sides and roof; contact metamorphism with indicator mineralisation and dyke intrusions.
