Depth of Slab Breakoff in the Archean: Radiogenic Heat and Oceanic Eclogitization
Understanding Slab Breakoff in Early Earth Continental collision is a fundamental process shaping Earth’s lithosphere. In the Archean, when crust was hotter and thinner, the mechanics of subduction and slab rollback differed markedly from the modern Earth. A pivotal aspect of this tectonic dance is slab breakoff: the detachment of a subducting slab from the…

From Mantle Flow to River Flow: How Earth’s Interior Shapes Surface Features
Introduction: Reading the Earth’s Hidden Currents The Earth’s surface bears the fingerprints of processes operating far below our feet. A new global synthesis, inspired by recent work featured in Geophysical Research Letters, connects the deep dynamics of mantle flow with the visible architecture of faults, fractures, and river systems. By tracing how the slow, buoyant…
