Extreme Heterogeneity in Mid‐Ocean Ridge Mantle Revealed in Lavas From the 8°20′N Near‐Axis Seamount Chain

Abstract Lavas that have erupted at near‐axis seamounts provide windows into mid‐ocean ridge mantle heterogeneity and melting systematics which are not easily observed on‐axis at fast‐spreading centers. Beneath ridges, most heterogeneity is obscured as magmas aggregate toward the ridge, where they e...
