"New Insights into Earth's Mysterious D” Layer from Ancient Ocean Relics"

A new study suggests that Earth's mysterious D” layer near the core-mantle boundary may have formed from a magma ocean created by a massive impact in the planet's early days. This layer's unique composition and heterogeneity could be explained by the presence of iron-magnesium peroxide, formed from water in the magma ocean, which has a strong affinity for iron and contributes to the D” layer's distinct geophysical features.

"Ancient Layer Discovered Deep Within Earth"

New research suggests that the mysterious D" layer deep within Earth may have formed from an ancient magma ocean, influenced by water, which led to the creation of iron-magnesium peroxide. This iron-rich phase could explain the layer's unevenness and the presence of ultra-low velocity zones, providing insights into Earth's early history and internal structure.

Scientists Uncover Origin of Mysterious Earth Layer

Geoscientists have potentially solved the mystery of the D" layer, a molten rock layer deep within the Earth, suggesting it was formed by a collision with a Mars-sized planet billions of years ago. This impact created a magma ocean, where unique chemical reactions led to the formation of an iron-rich phase called iron-magnesium peroxide, explaining the layer's seismic heterogeneity and varying thickness.
