Recumbent Fold at The Strangles

The sun has put her hat on and the country came out to play.  We went to the Strangles (a favourite) at a very low tide which allowed us to explore the most spectacular geology of the area.  Folds, folds and more folds, oh yes, and some sand and sea.

First, a scene setter:

So then, the folds.....  There are chevron folds, recumbent folds, overturned folds with convergent isogons (I think!).  Just so damned exciting, or is it just me.

Be like that then.  Let me change your mind:

So, here are the rocks of the Upper Carboniferous, squished into chevron folds WITH, yes WITH a recumbent fold that forms the roof of a natural arch.  I mean, come on!  It doesn't get much better than that!

Here's a closer view, in case you don't believe me:

Look, the rear of the recumbent fold looks cool too:

All these rocks were formed about 300 million years ago.

Things that make me go, "Hmm".  Fantastic.  Here endeth the geology lesson.

Do leave a comment; it's always nice to know someone's out there.
