Ayhan and Buyukkisla basins Central Anatolia
In June 2011, I spend two weeks in central Turkey to work with Eldert Advokaat on compressional and extensional basin evolution in upper Cretaceous to upper Eocene sediments around the Hirkadag massif of central Turkey. This fieldwork finished a paper that will be written by Eldert based on his MSc work in 2008 at Utrecht University (he is now headed for Royal Holloway university in London for a PhD on the geology of Sumatra). Our work in the basins occurred within the context of Come Lefebvre's PhD on the metamorphic and tectonic evolution of the Central Anatolian Crystalline Complex, and we got a nice complementary story out of the basins. The short version is that a late Cretaceous supradetachment basins near Ayhan got folded and thrusted during the late Eocene development of the Buyukkisla basin, whose stratigraphy is deformed into a major footwall syncline below basement and older sediments carrying thrusts. Below a short photo impression of the field trip.

Gotta look carefully, and you'll see a tight anticline, with an overturned limb on the right-hand side
