Geothermal Radiogenic Heat: The Silent Engine of Earth's Thermal Evolution

First Edition Manuscript. Radiogenic heat from the decay of uranium, thorium, and potassium isotopes is the silent engine behind Earth's thermal evolution. This book examines the isotopes that generate it, the rock physics that govern how it is produced, stored, and conducted through the crust, and the quantitative balance between radiogenic heat and tectonic heat flow.
