Mantle 'Chemical Patchiness': Study Provides First Direct Evidence of Its Spatial Scale

Mantle 'chemical patchiness': Study provides first direct evidence of its spatial scale

A joint research group has identified that the spatial scale of "heterogeneity" in the upper mantle, caused by a large-scale flow called a mantle plume rising from deep Earth, is less than 10 kilometers.

Direct Evidence Unveils the Spatial Scale of Mantle’s Chemical Patchiness

A groundbreaking study undertaken by a collaborative research team has transformed our understanding of the upper mantle’s structure, yielding significant insights into its heterogeneity. The joint effort included Senior Research Scientist Shiki Machida from the Next-Generation Marine Resources Research Center at Chiba Institute of Technology, alongside Professor Kyoko Okino from the Atmosphere and Ocean Research […]
