Metamorphic Geology & Tectonics of TÜRKIYE
This map of Turkey shows the location of some of the places my colleagues, students, and I have been working: various sites in the Central Anatolian Crystalline Complex (CACC, particularly the Nigde Massif); a complex of high-pressure rocks near the town of Sivrihisar (near the Izmir-Ankara-Erzincan suture); and the southern part of the Menderes Massif of western Turkey.
Central and western Anatolia contain metamorphic rocks and associated structures that formed during Alpine-Himalayan collision and subduction of Neotethyan seaways prior to collision. These rocks are spectacularly exposed, allowing us to link petrologic and kinematic history through time. Co-workers and I are studying the metamorphic rocks of central and western Turkey to better understand important questions in continental tectonics, such as
| What is the thermal and structural history of metamorphic rocks formed and exhumed in oblique tectonic settings? (wrench zones) | How do deformation and metamorphism interact during high-pressure metamorphism and exhumation in subduction zones? |
| What are the conditions, mechanisms, and time scales of orogenic crustal flow? | What are the processes that influence the preservation and/or overprinting of high-grade -- in particular, high-pressure -- metamorphic assemblages and textures? |
