Journey to the Roof of the World: how fast does the Pamir Frontal Thrust move?

Ben Johnson, a PhD student from the University of Oxford, describes his experiences from fieldwork over the summer of 2021. Read on to find out more about the Alai valley, glacial histories, and shortening across the northern margin of the Pamir.

The Pamir and Tien Shan are colliding along the Alai valley as part of the wider India-Eurasia continental collision. The Pamir are moving northwards along the Pamir Frontal Thrust (PFT), closing the valley. The rate of shortening across the PFT is contested, with short-term geodetic rates from GPS giving faster rates from those measured from palaeoseismology.

The COMET Central Asia Fault Database: Progress Report

The COMET Central Asia Fault Database integrates decades of fault mapping and field-studies by researchers from the UK NERC Centre for Observation and Modelling of Earthquakes, Volcanoes and Tectonics (COMET), and global collaborators.

Central Asia is home to one of the world’s great mountain ranges–the Tien Shan–which is formed by vigorous crustal convergence across a multitude of tectonic faults. Here we describe the motivation to assemble the database and the choices that we have made in its structure, which are based on utility, necessity, and limitations in available information. We are working towards a full public release of the dataset, so keep an eye out!

Video: Talk by Marc Jolivet about the Mesozoic and Cenozoic evolution of the Tien Shan

On 28 June, 2021, Marc Jolivet from Geosciences Rennes gave the third talk of our lecture series on the tectonics of Central Asia. The topic was The Mesozoic and Cenozoic tectonic, topographic, and climate evolution of the Tian Shan region: an insight from geomorphology and sediment analysis. In case you missed Marc’s presentation, here’s the video.
