Pillow Lava - Nare Head (S21)

Nare Head is formed from Volcanic Pillow Lava.
A view from below the cliffs at Nare Head , of a fine exposure of Pillow Lava.
During the Devonian Period Basalt Lava erupted into the sea forming rounded pillow shapes . As lava erupted on the ocean floor, its outer surface cools and solidifies forming a skin that surrounds the hot lava inside. Continued pressure of lava pushing from inside the flow causes the pillow to stretch and expand . New pillows form when hot lava bursts through the chilled skin of a previous pillow.
