These maps of major tectonic elements (plates, oceans, ridges, subduction zones, mountain belts) are used with permission from Dr. Ron Blakey at Northern Arizona University. The positions of mid-ocean ridges before 200 Ma are speculative. Click here for an explanation of map symbols.
Additional maps and Paleogeographic globes are available at Dr. Blakey's Global Earth History site.
