| Description: | For decades, seismic imaging and geochemical studies have revealed the presence of heterogeneity in the mantle at many scale lengths. Recent self-consistent, geodynamic plate-generation models match the longest wavelength features of tomographic spectra but the full spectrum of tomographic images and geochemical heterogeneity has yet to be fully explained by models of mantle dynamics. We invite contributions from seismologists, geochemists, mineral physicists, and geodynamicists to discuss the nature of the spectra of seismological and geochemical heterogeneity, both in the deep and the shallow mantle, and at global and regional scales. New perspectives on the techniques and experiments that may improve resolution and on conceptual efforts that would make the dynamic models more testable against the observations are especially welcome. |
