Plate Tectonic Reconstructions: Paleogene Period

Early Paleogene (Paleocene)

Late Paleogene (Oligocene)

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.
