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…

Depth of Slab Breakoff in the Archean: Radiogenic Heat and Eclogitization
Introduction: A Window into Early Plate Ttectonics The Archean Hadean to early Proterozoic transitional period remains a frontier in understanding plate tectonics. Among the most telling processes is slab breakoff, or slab detachment, during continental collision. By evaluating the depth at which breakoff occurred, geoscientists gain insight into how radiogenic heat production in the continental…

Depth of Slab Breakoff in Archean: Radiogenic Heat and Eclogitization in Early Continental Dynamics
Introduction: Why Slab Breakoff Matters in the Archean Continental collision in the early Earth often began with the subduction of oceanic lithosphere, but a dramatic and transformative process called slab breakoff or slab detachment could reshape tectonic evolution. In Archean settings, where crust was thicker, hotter, and more radiogenically active, slab breakoff likely occurred at…
