Cross-cutting dikes from Scotland

Imitating the detail of a tartan plaid, perhaps?

These perpendicular cross-cutting dikes were observed by NOVA associate professor of geology Victor Zabielski on a trip this summer to Scotland. Thanks for sharing, Victor!

A work of art

They don't make 'em like this any more. Check out how much information is infused into this one diagram, by Voll (1960) in a paper on the structural geology of the Scottish highlands:

Multiple generations of deformation overprint one another in a diagram that is at once informative and beautiful. It's a work of art. My geology M.S. advisor, Dazhi Jiang, shared this image with me once as an example of an elegant structural illustration. I think that it's just so good, that I have to share it at a larger size (rotated, so it will fit in the blog's space):
