Mapping deep mantle transition
The lower mantle is the liquid inner layer of Earth, between 400 and 1 800 miles below its surface. Seismic tomography has helped provide three-dimensional mapping of the lower mantle. However, the interpretation of models to highlight such factors as geochemical heterogeneity or dynamic mantle flow has been mixed, and ambiguous. The EU-funded DEEP-MAPS project provides for what its creators call a novel class of time-resolved experiments that will help map lower-mantle phase transitions, their impact on physical properties and their seismic signature. What is more, DEEP-MAPS will examine the time-dependence of each phase transition, contributing to better scaling of geological processes.
