Summary
[edit]DescriptionRipple marks in the Wrekin Quartzite - geograph.org.uk - 1379528.jpg |
English: Ripple marks in the Wrekin Quartzite High up on the side of the quarry face, there are a couple of rock exposures which clearly show underwater ripplemarks when the sediment was originally laid down, something like 540 million years ago during the early Cambrian era. Unfortunately the local 'yoof' have decided that it makes a handy place for painting and graffiti decoration. Not necessarily an improvement on the natural feature. |
