Scientists Depict the Nature of the Earth’s Lower Mantle Based on the Study of Mantle Plume Sources

Prof. TAO Yan from the Institute of Geochemistry collaborated with an international research team led by Prof. Keith Putirka from the California State University, Fresno to study the samples of volcanic rocks to achieve the goal of better constraining the mantle plume source, with the idea being that if plumes (Hawaii, Emeishan, Deccan, Baffin Island) truly originate from the lower mantle or core/mantle boundary, then they should be compositionally distinct from lavas ...
