Seismological expression of the iron spin crossover in ferropericlase in the Earth’s lower mantle

Posted by in category: futurism

This study identifies the predicted seismic expression of the high-to-low iron spin crossover in the deep Earth mineral ferropericlase. A depth-dependent signal is detected in the fastest and slowest regions, related to lateral temperature variations, of several global seismic tomography models.
