Coupled dynamics and evolution of primordial and recycled heterogeneity in Earth's lower mantle - Supplementary Videos

Anna J. P. Gülcher

Supplementary Videos

This .zip folder contains all Supplementary Videos related to the preprint "Coupled dynamics and evolution of primordial and recycled heterogeneity in Earth's lower mantle" by Gülcher et al. (in review for EGU: Solid Earth). Each regime discussed in this paper has been represented by a selected numerical model, displayed in all of the figures. For each of them, a video has been made showing the evolution through time of the primordial composition field as well as the potential temperature field. For the discussion of the evolution of these models, the reader is referred to the paper.
