Earth's mantle composition revealed by mantle plumes
Mantle plumes originate at depths near the core− mantle boundary (~ 2,800 km). As such,
they provide invaluable information about the composition of the deep mantle and insight …

A process-oriented approach to mantle geochemistry
A Stracke - Chemical Geology, 2021 - Elsevier
The numerous chemical and isotopic studies of oceanic basalts have shaped our perception
