| Pliocene - Miocene2.588 - 23.03 Ma | Miocene-Pliocene volcanic rocks Volcanic rocks May include hypabyssal intrusions. |
| Neogene2.588 - 23.03 Ma | Neogene sedimentary Sedimentary |
| Pliocene - Miocene2.588 - 23.03 Ma | Pliocene to middle Miocene deposits Major:: {conglomerate},Minor:: {sandstone},Incidental:: {gravel, sand, gypsum, limestone, mudstone, siltstone} Moderately to strongly consolidated conglomerate and sandstone deposited in basins during and after late Tertiary faulting. Includes lesser amounts of mudstone, siltstone, limestone, and gypsum. These deposits are generally light gray or tan. They commonly form high rounded hills and ridges in modern basins, and locally form prominent bluffs. Deposits of this unit are widely exposed in the dissected basins of southeastern and central Arizona. (2-16 Ma) In dissected basins of southeast and central Arizona |
