Booley Bay is home to some of the most amazing geology on the hook peninsula. Pictured below are Late Cambrian (approx. 500 million years ago) turbidites consisting of sandstones and shales. These rocks would have been deposited in a marine environment at a time when Ireland would have been located close to the south pole and completely under water!
We also see evidence of previous earthquake activity on Booley Bay in the form of normal faulting, here we can see how the rock has been displaced.
Finally another very interesting feature to be found in Booley Bay is what is known as Elephant Skin Mottling. This is said to be the related to microbial mat development, some of the earliest know life forms on the planet!
