Kink fold in Castner Marble
Posted by Callan Bentley
One more structure from the Castner Marble. This one is clearly tectonically-induced:
Top to the left! (East over west)

Son of a gun! I just noticed that I didn’t include a sense of scale here – that’s because it was up above, and unsafe to reach. The length of the short limb of the fold (width of the kink band) is between 2 and 4 inches.
I think I’ve been here … is this on a roadcut in the Franklin Mts just above El Paso?
Yes indeed. On the east side of the range, exposed on the north side of the road.
[…] back to my West Texas field trip now… remember the Castner Marble that we looked at earlier this week? Well, that very same marble is intruded by the Red Bluff Granite a bit further […]
