Weird Layered Rock
9Wednesday 04 November, 2015 by Uncle Spike
How about this for some strange geology?
Out and about the other week and I came across some ‘layered’ rock formations I hadn’t seen before. Each ‘layer’ was only say 5cm (2″) thick, but the twisted patterns and undulations must have an interesting tale to tell I suspect.

Any budding amatuer, or professional, geologists care to explain to the rest of us?

I am guessing at some ancient earth movement of course, as this whole area of the Near Middle East is very prone to earthquakes, even today.

I fall into the budding amateur category, so I can tell you a little. Originally all the layers were flat and forces in the earth’s crust caused by tectonic movements bent and cracked the rocks. The forces have different effects depending on conditions such as heat, rock type, and the pace of deformation. The folds probably happened slowly while the cracks/faults would have happened relatively fast (earthquakes).
As for the rock type, it’s hard to see in the photos, but you’re probably not far off when you say shale.

Thank you so much… makes a lot of sense too. What an amazing planet we have!

Shale?? Just a guess and I will be sure to check back to see what others say…

Could be. Thought it was too thick for shale, but looking on Google there are thicker examples. Not seen shale so twisted before either. Interesting stuff indeed 🙂

I hope someone comes along to explain the forces that were at work here. I can’t begin to imagine the temperatures and thrusts that must have been present.
