Global Tectonics

  1. 1. Global Tectonic reconstructions are from the website of Dr. Ron Blakey at N.Arizona University These are by far the best reconstructions I have found http://cpgeosystems.com Colorado Plateau Geosystems Four maps at the end are from www.Scotese.com a tectonic website well worth a visit, they have good animations and reconstructions as well Enjoy! -Carter Keairns 512-757-0735 carteroil@yahoo.com
