The distribution and composition of high-velocity lower crust across the continental U.S.: comparison of seismic and xenolith data and implications for lithospheric dynamics and history

Editors’ Highlight—        This paper presents an analysis of the crustal structure beneath the continental US, combining geochemistry with geophysics. The authors use receiver functions, Vs derived from surface waves, and xenoliths to infer the composition and velocity structure of the lower crust..... more

Unraveling the History of the India-Asia Collision

Terri Cook, Freelance Writer

From Research Spotlights— 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.  The lofty Himalaya, which stretch nearly 3000 kilometers.... more

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

Terri Cook, Freelance Writer

From Research Spotlights— 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.  The island of Taiwan has been actively uplifted since the collision of a volcanic.... more

On the Origin of Low-Angle Detachment Faults

Terri Cook, Freelance Writer

From Research Spotlights— 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. Seismologic evidence has consistently shown that displacement on normal faults.... more

Characterizing the Faults Beneath Germany

Shannon Hall, Freelance Writer

From Research Spotlights— A team of researchers has described how the faults within the German Alpine Molasse Basin initially developed.     As Europe flexed down under the weight of the Alps, a foreland basin—the German Alpine Molasse, which today extends from Switzerland in the west to the.... more
