What Does EM Stand For?
EM stands for Enriched Mantle
Enriched Mantle (EM) refers to a section of Earth's mantle that is compositionally distinct due to the presence of materials derived from subducted oceanic crust and sediments. This region is characterized by higher concentrations of incompatible elements, indicating a history of partial melting and metasomatism. The EM plays a crucial role in understanding mantle dynamics, magmatic processes, and the evolution of tectonic plates, contributing to our knowledge of planetary geology and geochemical cycles.
