New potassium-argon age data from the Columbia Plateau suggest a basalt production rate of 108 cubic meters per year during a middle Miocene volcanic episode. This is two to three times the production rate in some oceanic islands, and about four to six times the production rate in spreading mid-oceanic ridge systems.
