Permian

251.902 - 298.9 Ma

ID: 3187666

Paleozoic sedimentary rocks

Age: Phanerozoic (251.902 - 298.9 Ma)

Lithology: Sedimentary rocks

Serpukhovian - Early Cambrian

323.2 - 541 Ma

ID: 2976886

Mississippian, Devonian, and Cambrian sedimentary rocks

Age: Paleozoic (323.2 - 541 Ma)

Stratigraphic Name: Tapeats Sandstone; Bright Angel Shale; Muav Limestone; Temple Butte Formation; Redwall Limestone; Bolsa Quartzite; Abrigo Formation; Martin Formation; Escabrosa Limestone

Description: Brown to dark gray sandstone grades upward into green and gray shale, overlain by light to medium gray or tan limestone and dolostone. This unit includes the Tapeats Sandstone, Bright Angel Shale, Muav Limestone, Temple Butte Formation and Redwall Limestone in northern Arizona, and the Bolsa Quartzite, Abrigo Formation, Martin Formation, and Escabrosa Limestone in southern Arizona. These rocks record intermittent sea-level rise and inundation in early Paleozoic time. (330-540 Ma)
