  Lower Mesozoic clastic rocks that unconformably overlie Paleozoic rocks within the Northern Sierra terrane provide clues regarding the evolution of the terrane during a 60 m.y. interval spanning the late Carnian through Bajocian.

Geology (from the Ancient Greek γῆ, gē ("earth") and -λoγία, -logia, ("study of", "discourse")) is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time. Geology can also include the study of the solid features of any terrestrial planet or natural satellite such as Mars or the Moon. Arizona sits astride two major geologic provinces, the Colorado Plateau to the north and the Basin and Range to the south and west. The Plateau Province includes the northern third of the state bounded on the south by the Mogollon Rim and on the west by the Grand Wash Cliffs (land form is characterized by sedimentary rocks, with canyons, plateaus, and scarps.) in the western Grand Canyon.

Rocks mapped as Mesozoic cover much of the Plateau and crop out in numerous areas within southeastern and southwestern Arizona, but they are scarce or lacking within central portions of the State, as shown on the County Geologic Maps* and the Map of Outcrops of Paleozoic and Mesozoic Rocks in Arizona*.
