Early Paleozoic ridge subduction in the Chinese Altai: insight from the abrupt change in zircon Hf isotopic compositions
Zircons were separated from granitoids, gneisses, and sedimentary rocks of the Chinese
Altai. Those with igneous characteristics yielded U-Pb ages of 280–2800 Ma, recording a …

Changing exhumation patterns during Cenozoic growth and glaciation of the Alaska Range: Insights from detrital thermochronology and geochronology
Cenozoic growth of the Alaska Range created the highest topography in North America, but
the space‐time pattern and drivers of exhumation are poorly constrained. We analyzed U/Pb …

Architecture of the Chugach accretionary complex as revealed by detrital zircon ages and lithologic variations: Evidence for Mesozoic subduction erosion in south …
Subduction erosion is an important process at convergent margins but evidence in the
geologic record is scarce because the involved materials are typically lost into the mantle …
