My project: Cenozoic crustal thickening and gneiss-dome exhumation in the Central Pamir

I am working in the tajik Central Pamir with a focus on the Cenozoic burial and exhumation of the (east to west) Shatput, Muskol, Sares and Yasgulem domes. The Pamir is situated above the western Syntax of the India-Asia collisional system. The Pamir is an exceptional orogen in several respects: It hosts one of the few intracontinental intermediate depth seismicity zones on the planet, interpreted as an intracontinental subduction by some researchers. It belongs to the most S-N shortened part of the India-Asia collisional system offering a window into deep crustal processes through the Neogene exhumation of "my" domes (in contrast to Tibet). The boundary between externally drained mountain belt (western Pamir) and internally drained plateau (Eastern Pamir) runs through the middle of my working area.

Methodologic work: The irradiation parameter 'J'

I am trying to better understand the irradiation parameter 'J' in Ar-Ar dating, Neutron fluence gradients and find alternative fluence monitors.

The methods I am using to answer my research questions:

Classical field geology including mapping and structural analysis
Microtectonic analysis
Ar-Ar thermochronology
U-Pb zircon geochronology
beta and gamma-spectroscopy
