Colorado Plateau Geosystems, Inc. ™
Colorado Plateau Geosystems Inc provides paleogeographic maps of the ancient world. The paleogeographic maps show the varied landscapes of the ancient Earth through hundreds of millions of years of geologic time, including distribution of ancient shallow seas, deep ocean basins, mountain ranges, coastal plains, and continental interiors. Tectonic features shown include subduction zones, island arcs, mid-ocean ridges and accreting terranes. Latest geologic data from the scientific literature are used to compile and construct the ancient Earth.
Paleogeographic maps have multiple uses. Paleogeography is a synthesis and can only be accomplished from extensive geologic data. Therefore, paleogeographic maps portray immense amounts of data in a single view. This may be their single greatest value. They also show this data in a way that is interpretable to non-geologists. When used in time sequence, they show trend and pattern through geologic time. They readily display distribution of ancient geologic features at the surface of the Earth. They teach both geologists and non-geologists broad patterns of Earth history. They help satisfy our curiosity concerning what the Earth used to look like - they educate and stimulate.
Ronald Blakey, Professor Emeritus NAU Geology has spent over 20 years creating these paleogeographic maps. Dr. Blakey's maps appear in numerous books, professional publications, visitor centers and museums throughout the world. His professional career involves the study of the stratigraphy and sedimentology of the ancient rocks of the Colorado Plateau.
*NEW* A completely revised North American series, Key Time slices of North American Geologic History ©, that includes 36 time slices, 15 facies-tectonic maps, and 16 plate-tectonic maps. The paleogeographic maps have nearly twice the resolution of the previous North American series (the older series with 93 time slices is still available -- the tight spacing of the time slices in the older series makes it a good DVD from which to make animations). The Key Time slices of North American Geologic History © DVD incorporates new data, new models, improved construction methods, and crisp map images.
