Scientists know that manganese, in its various oxide forms, plays a significant role in Earth's geochemical cycles. However, the exact forms of manganese, their abundance and the mechanisms behind these cycles that occur in Earth's deep, high-pressure interior are not well understood. But, a recent study, published in Physical Review B, reports on a newly discovered manganese rich compound that might help shed light on manganese's behavior in Earth's interior and explain why seismic waves slow down in certain regions.
