...Stephen T. Nelson; Garret L. Hart; Carol D. Frost Abstract A separate basement terrane, Mojavia or the Mojave province with characteristic 2.0–2.3 Ga model ages, has been proposed to underlie much of the western U.S. Its existence, posited on patterns of Pb and Nd isotope data, has been propagated...

... with Paleoproterozoic accretion of Mojavia (±Yavapai-Colorado) to the Wyoming Province. Crystallization and model ages of the Farmington sequence suggest a possible genetic link between Mojavia, the Farmington zone, and the Wyoming Province, which would provide new constraints on proposed Neoproterozoic conjugates...
