Quaternary extrusion rates from the Cascade Range, northwestern United States and British Columbia
Sherrod DR and Smith JG. 1990. Quaternary extrusion rates from the Cascade Range, northwestern United States and British Columbia. Journal of Geophysical Research. 95(B12):19465-19774
The Quaternary extrusion rate and style of eruption for the Cascade Range changes abruptly along the length of the volcanic arc. Quaternary extrusion rate correlates closely with regional heat flow, and different rates likely indicate zones of differing heat input. Volcanic style changes at different latitudes, which may signifiy diffuse versus focused heat sources or crustal changes in permeability to ascending magma along the arc. Both extrusion rate and volcanic style may be significant in the search for exploitable geothermal energy. Although volcanism in British Columbia, Washington, Oregon are focused on, data for Lassen Peak is presented as well.
