摘要: The Basin and Range province has been the site of extensional orogeny for past 40 m.y. Its complexities may be caused by superposition three tectonic regimes: (a) an Andean-type volcanic arc, which gradually gave way to (b) a spreading ensialic backarc basin was in turn succeeded (c) intraplate block faulting rifting. Total extension have exceeded 100 percent.
