Central Pamir, Tajikistan
Detrital geochronology and terrane correlation
How do the fragments of continental crust that make up the himalayan belt all fit together? Efforts to relate geological units between the Pamir and Tibetan Plateau are hindered by right-lateral offset along the Karakoram Fault, and the development of the northwards-convex Pamir salient. Despite recent advances, inadequate documentation of rock units in the Central Pamirpresents a significant obstacle in evaluating how Pamir geology relates to that in Tibet, and thus in understanding the evolution of the Tibet–Pamir orogenic system as a whole. This project involved geologic mapping, detrital zircon U-Pb, Lu-Hf geochronology, and sedimentary and metamorphic petrography south of the Muskol metamorphic dome in the Central Pamir terrane to provide new constraints on the evolution of the Pamir orogen from Triassic to Late Oligocene time.
