Syncline: Great Orme

We walked under the impressive limestone cliffs on the Great Orme at Llandudno. Look at the angle of the layers in the photograph. Limestone is sedimentary and must be laid in horizontal beds on the bottom of the sea. Earth movements can then bend these layers. Here the layers are heading downwards. The Great Orme is said to be part of a syncline, where rock goes down on one side and then comes back up. I learned a new term researching this: Dinantian. The part of the Carboniferous age when these rock were made. http://geoscience.wales/wp-content/uploads/2016/12/Llandudno-August-Field-excursion.pdf
