Zanclean - Tortonian
3.6 - 11.62 Ma

ID: 3016466
Pliocene to late Miocene basaltic rocks

Age: Neogene (3.6 - 11.62 Ma)

Description: Mostly dark, inconspicuously flat, low-lying or mesa-forming basalt deposited as lava flows. Rocks included in this unit are located almost entirely in the large volcanic fields south and west of Flagstaff, in smaller fields in northwesternmost Arizona, and in the Hopi Buttes volcanic field on the Navajo and Hopi Indian Reservations north of Holbrook. Original volcanic landforms have been obscured by erosion. (4-8 Ma)

Comments: Chiefly Hopi Buttes, "Rim basalts", volcanic fields in northwesternmost Arizona Original map source: Arizona Geological Survey, DI-8 Geologic Map of Arizona, Digital Spatial data for the Geologic Map of Arizona, v. 3.0, edited by S.M. Richard and S.M. Kneale, 2002, 10 p., 2 DOS HD disks. Arc/INFO export file (.e00) format, scale 1:1,000,000.

5.333 - 23.03 Ma

ID: 3352919
Mafic monchiquite and basanite flows

Age: Miocene (5.333 - 23.03 Ma)

Description: Black, dark-gray, and brown porphyritic monchiquite and basanite. Contains olivine, clinopyroxene, and phlogopite phenocrysts. Thick monchiquite flows display prominent columnar cooling joints. Includes xenoliths of crystalline metamorphic rocks near vent areas on Wood Chop Mesa (fig. 1; sheet 2). Include abundant kaersutite megacrysts near top of some bedded deposits in Wood Chop Mesa area. 40Ar/39Ar age on kaersutite about 0.7 km (0.5 mi) east of Wood Chop Mesa (just east of sheet 2) is 6.81±0.06 Ma (Vazquez, 1999). 40Ar/39Ar ages of basanite flows in Wood Chop Mesa area are 6.99±0.75 Ma, 6.53±0.59 Ma, and 7.21±0.45 Ma (Vasquez, 1999). Thickness, 3 to 43+ m (6 to 140+ ft)

Comments: Volcanic rocks of Hopi Buttes (Tsezhin Bii) Volcanic Field (Miocene)—Unit was originally defined as the middle volcanic member of the Bidahochi Formation (Repenning and Irwin, 1954; Shoemaker and others, 1957, 1962); however, we herein redefine them as the volcanic rocks of Hopi Buttes Volcanic Field because it forms a mappable sequence of volcanic rocks that intertongues with deposits of the lower Bidahochi Formation (Tbl) of Miocene age near White Cone Peak northeast of quadrangle and in northeast quarter of quadrangle (sheet 2)
