Key Points

This research aims to explore the role of hydrous ferropericlase in deep Earth’s low-velocity anomalies and its implications for the core–mantle boundary.
Conducted HPHT experiments to simulate deep Earth conditions.
Utilized NanoSIMS for analysis of hydrous ferropericlase's properties.
Hydrous ferropericlase acts as an efficient water reservoir in the basal magma ocean.
Provides a new explanation for the origin of Earth’s deep low-velocity anomalies.

Implication

HPHT experiments reveal hydrous ferropericlase’s role as an efficient water reservoir, indicating implications for Earth’s core–mantle boundary.

Abstract

HPHT experiments assisted with NanoSIMS demonstrate that hydrous ferropericlase, stable in the early basal magma ocean, is an efficient water reservoir and may provide a new explanation for the origin of Earth’s deep low-velocity anomalies.
