Some geology
« on: May 22, 2017, 09:07:58 am »

The SW coast of Portugal features some interesting geological "landscapes". As a photographer, I normally turn towards the sea; as a geologist, I have to turn towards the cliffs:)

This particular session, I went to this beach near Almograve, during sunset time. The air was very hazy (I suspect dust from North Africa, the weather was very windy), making for somewhat bland skies. Nevertheless, the folds in the rocks make for interesting subjects.

Kind regards.

Thanks for sharing, they are really interesting and very different from your ocean shots.

Indeed. I might try getting closer, especially when the skies are uninteresting. On the plus side, these skies provide even lighting of the rocks.

+1. I'd try cropping out the sky completely.

I'm glad I wasn't present when those folds actually occurred! They are spectacular.

Fun shots Paulo.  Mind commenting a bit on the geology to satisfy a fellow geoscientist?  After all we share conjugate margins  :)

Of course. These are mostly Carboniferous formations, with varying degrees of metamorphism and affected by the Variscan orogeny.

Here are some links for your perusal:

Is it wrong that I'm attracted to the first formation?  ;)

No Matt... Georgia would be proud of you!!  ;D


By the way Paulo, is there a K-T line in any of that?

Very interesting! I suppose that I would be snooping at close range, hoping to see a fossil or two.

Thanks for the links Paulo.  I particularly enjoyed the last one.  I have known Haakon for a long time and have been co-authored a couple of papers with him.

Nope, these are much older, Carboniferous rocks.

Not much to see in terms of fossils here, the odd plant and/or trace fossils sometimes.
