Abstract

I study the structural inventory, kinematics and geo-/thermochronological evolution of NE-Afghanistan. I test the model of Stübner et al. (2013a,b) which proposes the transfer of deformation from the extensional Shakhdara dome into the compressional Tadjik-Afghan-Basin by ductile crustal flow in NE-Afghanistan. The methods I use are structural mapping of the working area, petrological and microtectonic analyses of thin sections and the application of multiple thermochronometers (Apatite Fission Track, Zircon-Uranium-Lead, Argon-Argon, Uranium-Thorium-Helium).

The Pamir shows the highest amount of N-S shortening within the shortest distance in the India-Asia collisional system. The orogen hosts one of the two intracontinental intermediate depth seismicity zones. This makes the Pamir an interesting natural laboratory for studying the deformational behavior of the lithosphere. In NE-Afghanistan one can study the sutures and geological units along a c. 200 km long W-E profile which, elsewhere in the Pamir Mountains, exclusively can be observed over a range of several thousands of kilometers (Tapponnier et al. 1981). Therefore, my working area plays a key role in understanding the India-Asia collision. Today’s convergence rates were measured using GPS (Mohadjer et al. 2010). Shortening which cannot be linked to known active fault zones, are located within the Central Pamir (16±2 mm/a) and the Hindu Kush. At the moment one cannot clearly distinguish the amounts of total shortening which are accommodated in the Pamir and at its borders. Additionally, the amount of the displacement along the main fault zones in the Hindu Kush and Tibet does not sum up to explain the total convergence throughout the India-Asia deformation zone (Mohadjer et al. 2010) This indicates the presence of yet unknown, active structures in my working area.
