The smallest boudinage (sounds like a kid's book doesn't it?)
Cap de Creus
But for anyone who is interested to know a little bit about the geological setting of the area (and I guess there aren’t so many of you who are but bear with me =), the Cap de Creus Penninsula is the eastern-most outcrop of the Variscan Axial Zone of the Pyrenees (yes I got that straight from the excursion-book). The cape has undergone a number of periods of deformation leaving it metamorphosed and extremely deformed. The thing is, there is so much happening there that it is sometimes very hard to work out what is actually going on. Also, since the lithology is dominantly turbidites it is almost impossible to follow any of the beds along, so there has not been much done on the lithology.
More Cap de Creus
A nice rocky view of Cap de Creus. Now that I have been looking at more Salvador Dalí artwork I think it is a bit like some of the backgrounds in his paintings (but I will get to Dalí later).
At the end of the first day we went up to the bar that is next to the lighthouse for a beer. Of course it started raining but the view was so amazing that we sat outside anyway. And here it is:
The view from the bar.
Apparently when Paul is running excursions for undergrads he sits up there with a beer and can see what they are doing. Pretty good vantage point.
The second day we went a bit further inland, to Mas Rabbassers de Dalt which is the ruin of an old farmhouse, with some structures nearby that are perfect for kinematic analysis.
Geologists doing what geologists do best.
The ruined farmhouse.
It was at these ruins that we got to experience the start of Tramuntana, an extremely powerful wind that makes you want to go inside and have a beer (unless of course there are amazing structures to view). Fortunately it was not at its worst apparently (I would seriously hate to see it then… I felt like I was going to be blown off the rocks and into the water as it was).
Then we came across absolutely the cutest thing I’ve ever seen (except for Jesper of course ;). A teeny-weeny boudinage. Now any of the geologists out there will know that boudinage is an effect you get in a deformed layer, where it becomes stretched and blobs form with very thin umbilicous joining them. Often these seperate boudins rotate due to deformation and so you can work out the stress field that has affected that area by looking at the way they have rotated, thus determining things about the bigger tectonic picture from just a tiny structure. And how cute are they:
The littlest boudinage (with a coin for scale).
Okay… yes you may think I’m strange but usually you don’t see these so lovely and small and perfect… alright… I guess I’m not digging myself out of the weird rock person hole, so I think I will just dig a bit further (I’m a geologist after all) and show you some almost as cute ptygmatically folded quartz veins.

At one point that clouds lifted and we got a lovely view of the

When the wind finally got too much we headed back to our bungalows. And so another geologically perfect day ended as most do… with a beer.
