Mount Washington 4: folded granite dikes
We now return to Mount Washington, New Hampshire, where our intrepid heroes summit the mountain in a mere three hours (from Pinkham Notch via the Lion Head): To refresh your memory of the story so far, we had seen metamorphosed turbidites, like this one (new image): …and checked out some gorgeous metamorphic porphyroblasts of “pseudoandalusite,” … Read more
Mount Washington 3: turbidites and their metamorphism
After my cousin Brad caught up with us after our Pinkham Notch roadcut excursion, we started up the trail at Tuckerman Ravine, and then detoured to go via the Lion Head. Immediately, we began to see some freaking awesome metamorphic porphyroblasts. During the Acadian Orogeny (in the late Devonian), the original muds and sands (deep … Read more
Friday fold(s): Mount Washington 2
More from Mount Washington, New Hampshire: some folds in the Madison Member of the Littleton Formation (schist) along the auto road near Cragway Springs (just past 5 miles up; see map below): IMAGE SOURCE The folds are asymmetrical, with long west-dipping limbs, and shorter east-dipping limbs. Happy Friday!
Capadoccia 7
And now, for the final half of my final day in Capadoccia, Turkey… We continued hiking along up the scenic valley that I mentioned a few days ago, checking out the lovely scene in the lovely weather… The valley floor was reasonably wet and vegetated, but the higher slopes were eroding at a rate too … Read more
Capadoccia 6
I’ve got two more batches of Capadoccia photos for you. Sorry if you feel bored with this continuing series — but I think it was not only my favorite part of Turkey (and geomorphologically interesting) but photogenic too… So on our final day in Capadoccia, Lily and I took a hike up another valley. We … Read more
Capadoccia 5
So where did we leave off with the Capadoccia photos? I think we mentioned a hike, right? Here’s Lily buying orange juice from two boys who operated a refreshment stand in the middle of nowhere. There was a lot of good, fresh fruit in this dry land, a fact which surprised me. Here’s some apricots … Read more
Capadoccia 4
On our second day in Capadoccia, Lily and I went for a walk through one of the valleys that are eroded into the landscape there. Bas-relief hoodoos emerging from the wall of the canyon: We came to one area with classic turret-like hoodoos: Note the gravel layers in that column’s section, and the human at … Read more
Capadoccia 3
Callan shares some more images from last summer’s trip to Capadoccia, Turkey. Eroded turrets of ignimbrite served as dwellings for Byzantine-era Christians, who decorated them with distinctive art.
Capadoccia 2b – panorama
Click this image to go to a big panorama (but not big enough to be hosted by Gigapan) of one of the valleys near Göreme, Capadoccia, Turkey: Note: The agriculture that lines the bottom of the valley. The colors of the tuff, and how they vary from place to place. The differentially eroding layer that … Read more
GoSF4: Kirby Cove
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.
Travels of 2010
I’ve been asked to put up a post detailing travels from the year now concluding. You got it! The first day of January dawned for me in Buenos Aires, Argentina. 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
Gravel and sand
Another image from Turkey… Tell me, fluvial folks and sedimentary soothsayers, what do you see here? Here’s a bigger version, if that helps.
Gerede segment of the North Anatolian Fault
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.
Scenes from the Virginia Museum of Natural History
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.
Tavşanlı Zone field trip, part 7
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.
Extended tomb
This summer, strolling atop the massive travertine terraces of Pamukkale, Turkey, I checked out the necropolis (graveyard) of Hierapolis, an ancient city founded around 200 BCE and abandoned after an earthquake in 1534. One thing that caught my eye there was this tomb, built of travertine blocks.
Joint sets at Pamukkale, Turkey
A lot on my plate today, so I’m just going to toss a random photo from my summer trip to Turkey up on the blog for today. This is a block of building stone at Hierapolis, the Greek spa resort atop the travertine mounds of Pamukkale, in central Turkey (near the town of Denizli). Check … Read more
