Coverack Guided Geowalk (half-day) Saturday 9th August 2025

Taking a trip Coverack is also a journey deep inside the Earth! Here you can traverse the boundary between the Earth’s oceanic crust and mantle, discover the origins of the exotic rocks that make up the Lizard Peninsula, and learn of their journey to where we see them today on the Cornish coast.

What to expect

The Lizard Ophiolite – The breadth of Cornish geology even includes its own ophiolite – a fragment of oceanic crust! Examine rocks that formed deep inside the Earth, and learn how at Coverack they tell us they formed at the Moho – the boundary between the Earth’s crust and mantle.

The story of serpentine – Discover of the origins of this rock that the Lizard is most famous for. Learn about the processes that gave us this popular ornamental stone, and its other uses as a source of industrial minerals.
