Unraveling the History of the India-Asia Collision

by Terri Cook 15 May 201713 April 2022

A study of deformed and metamorphosed rocks exposed in Tibet’s Lopu Range suggests that episodes of crustal shortening and extension during the evolution of the Himalaya are related to subduction processes.

Reinterpreting the Age and Origins of Taiwan’s Yuli Belt Terrane

by Terri Cook 4 May 201726 January 2023

Uranium-lead dating of zircons from Taiwan’s east central metamorphic belt offers robust evidence that this uplifted terrane is some 90 million years younger than previously thought.

Researchers trace the history of California’s Whipple Mountains and find a new relationship between normal and detachment faults.

On the Origin of Low-Angle Detachment Faults

by Terri Cook 7 March 20176 October 2021

Data from California's Whipple Mountains suggest this complex was formed by a succession of steep normal faults, challenging the paradigm that detachments are different types of faults.
