While documenting a procedure at Ian’s boat the other day, I had the opportunity to take a few photos of some of the local rock structures. I found these particular rocks, which had been exposed when the owners of the boatyard wanted to extend their working space, and just had to photograph them.
I believe these rocks are shale, but I am not a geologist. The whole rocky outcrop looked amazing, the colours of the shale quite bright and beautiful. I read that the yellow colours are caused by iron oxide or iron hydroxide which can cause reddish, yellow or brown colouring. The shale came apart in my hands, very poorly compacted material.
Ireland is an excellent place, like so many other places on the earth, to look at and have an interest in rocks and minerals. I have a large rock collection, I only wish that I knew more about it all, something that I always wanted to get absorbed in when I retired. It is a fascinating subject with plenty of examples all around us.
