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 nearly 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.

Paleogeography

Paleogeography is the study of the geography of the ancient Earth. The paleogeographic maps on this site are representative of my many years of constructing these maps. They are made by plotting data and interpretations from the geologic literature and then painting the paleogeographic maps to look like satellite views of Earth's past. Thousands of publications were used in constructing these maps and a few key references are given at the bottom of the "Paleogeographic Maps" page. The ages in millions (Ma) and Billions (Ga) of years ago and their correlation to the names on the geologic timescale are from the 2004 Timescale (Gradstein, et al.). This geologic time scale is also shown on the "Paleogeographic Maps" page.
