Although variations in insolation and emergent feedbacks among soil moisture,
vegetation, and soil cohesion are commonly invoked to explain topographic asymmetry that
depends on aspect, few studies have directly quantified the efficiency of regolith transport along
hillslopes of opposing aspect. We utilize meteoric ¹⁰Be concentrations in regolith (n = 74)...
A fundamental debate exists regarding the geometry and depth extent of seismogenic faults in eastern Tibet. Along the Longmen Shan, geologic and seismic reflection data reveal a belt of low to moderate angle thrust faults, some of which may have been activated in devastating earthquakes in 2008 (Mw ~7.9, Wenchuan)...
Controversial end member models for the growth and evolution of the Tibetan Plateau demand quantitative constraints of the lithospheric rheology. Direct determinations of bulk crustal rheology, however, remain relatively sparse. Here we use the flexural rebound of lacustrine shorelines developed during the Lingtong highstand around Siling Co, in central Tibet,...

Although geodetic measurements of interseismic deformation in interior Tibet suggest slow
strain accumulation, active slip along the right-lateral Gyaring Co Fault is suggested to be between 8
and 21 mm/yr. Reliable geologic constraints on the slip rate along this fault are sparse. Here we document
12 ± 2 m of...

In the Colorado Rocky Mountains, the association of high topography and low seismic
velocity in the underlying mantle suggests that recent changes in lithospheric buoyancy may have
been associated with surface uplift of the range. This paper examines the relationships among
late Cenozoic fluvial incision, channel steepness, and mantle velocity...

Pleistocene drainage basin integration led to progressive excavation of
Tertiary-Quaternary sedimentary basins along the Yellow River in the northeastern Tibetan
Plateau. Cosmogenic burial dating of ancestral river deposits and basin fill from two key
watershed divides confirms a fluvial connection between basins at 0.5–1.2 Ma, prior to excavation
by the...
