Determining Mantle Temperature and Composition from Discontinuities part of Cutting Edge:Deep Earth:Activities
This pair of activities uses observations of mantle discontinuity structure to examine mantle heterogeneity and differences in the depth extent of melt sources for ridges and "hotspots." The first activity focuses on interpretations linked with temperature anomalies, and the second activity emphasizes that contributions from variable composition (iron and water) are important to consider as well.
