This presentation uses a series of paleogeographic and plate-tectonic reconstructions to show the broad patterns of Phanerozoic Earth history. Subject matter ranges from the scale of continents, to parts of continents, to orogens. Organization for each region is in geologic order from oldest to youngest.
40 images track the geologic evolution of North America.
Detailed paleogeography of Colorado Plateau, Southern Rocky Mountains, and portions of Basin and Range.
Basins, uplifts, tectonic evolution, and paleogeography of greater Ancestral Rocky Mountains.
Controversial assembly of Western North America during Mesozoic.
Tectonism, volcanism, sedimentation, and paleogeography of the Mogollon Rim and adjacent central Arizona.
Older, lower-resolution maps of Europe, Asia, North Atlantic, and global spheres. Many of these maps will be replaced by new maps in the future.
