It is old red sandstone that is mainly found on the surface here in West Cork. And this Red sandstone is covered generally by carboniferous limestone. There are also areas of Carboniferous shales and slates. I don’t know that much about geology yet, but I am very interested in learning more, especially as I have an extensive collection of rocks in my living room. Collected over the years, some from all over the world when I travelled. I found my first fossil when I was eleven years old. Rocks are fascinating, they are ancient and their mineral composition is interesting. I always thought that when I retired I would find the time to take up geology and identify all my rocks. So far that has not happened in a serious way, but it will. I will do a course online or something and learn a lot hopefully. 🙂
These rocks I found mainly at Kilbritain beach County Cork.
