Continental vs oceanic lithosphere

WebOceanic Lithosphere. Oceanic lithosphere is produced at ocean ridges and cools, thickens, and increases in age as it moves away from ridges. The standard model involves cooling by conduction and increasing in thickness until about 70 Ma, reaching a maximum thickness of about 120 km. In contrast, the underlying asthenosphere is mixed by shallow ... WebDec 1, 2024 · A comparison of oceanic and continental mantle lithosphere. 1. Introduction to the lithosphere. Constraints on the boundary layers of the convecting mantle, including the outermost boundary layer that coincides with the lithosphere, are crucial for understanding plate tectonics and mantle dynamics.
