Upper-Mantle Origin of the Yellowstone Hotspot

Christiansen Robert, U.S. Geological Survey

This online report describes a model in which the Yellowstone hotspot is caused by upper-mantle convection and regional tectonics, contradicting the deep-mantle plume model proposed by others. Numerous lines of evidence are presented in support of this model. Discussions of the Yellowstone hotspot, geologic constraints, seismic imaging, and helium geochemistry are provided among others. The report is available in HTML and PDF formats.
