This document discusses key concepts in geodynamics including large low shear-wave velocity provinces beneath Africa and the Pacific known as Tuzo and Jason that may be plume generation zones related to large igneous provinces and volcanic exhalative processes. It examines large low shear-wave velocity provinces and their potential connections to mantle plumes, hotspot volcanism, and volcanic exhalative processes.
