Though largely inaccessible, the geochemistry of Earth's mantle and core can be
examined through a wide variety of approaches. Volume 2 focuses first on
"remote" sensing using evidence from cosmochemical, seismic, petrologic and
geochemical approaches. Mantle composition is then examined in detail through
descriptions of mantle samples brought to Earth's surface through tectonic,
volcanic, and volatile-outgassing processes. The volume concludes with
examination of processes that modify the composition of the mantle and core
including an early magma ocean, partial melting, element partitioning between
minerals and melts, and physical mixing caused by plate subduction, mantle
convection and mass exchange between mantle and core.
