The colors of the tuff, and how they vary from place to place. The differentially eroding layer that … Read more
Part 4 of the ongoing series examining the geology of the San Francisco area. In today’s post, Callan visits Kirby Cove in the Marin Headlands, where intensely deformed chert can be found on one end of the cove, pillow basalts on the other, and an “artificial dune” in the middle.

I had just gotten done with one of the best trips I’ve ever taken, to Patagonia in December 2009. The capital of Argentina was a … Read more
Another image from Turkey… Tell me, fluvial folks and sedimentary soothsayers, what do you see here? Here’s a bigger version, if that helps.
The author recounts a field trip in October along the section of Turkey’s North Anatolian Fault that last ruptured in 1944. The rock types on either side of the fault are compared, offset markers are illustrated, and several types of landforms particular to strike-slip faults are shown. The post concludes with an examination of the town of Gerede itself, which is built directly atop the fault.
The author describes a quick visit to the Virginia Museum of Natural History in Martinsville, Virginia, on his way back to DC from Thanksgiving travel. Highlights: a dinosaur, a giant stromatolite, encrusting crinoids (they do that?) and a giant ground sloth.
Part 6 of the Tavşanlı Zone field trip had us looking at some blueschists and eclogites. Today we conclude the terrific field trip with a brief look at a couple more stops.
