The Basin and Range-Colorado Plateau transition zone is a broad region in central Utah containing structural and stratigraphic characteristics of both the Basin and Range Province to the west and the Colorado Plateau province to the east.

The boundaries are the subject of some disagreement, resulting in various interpretations using different criteria.

Essentially, extensional tectonics of the Basin and Range has been superimposed upon the adjacent coeval uplifted blocks of the Colorado Plateau and Middle Rocky Mountains.

The result is that block faulting, the principal feature of the Basin and Range, extends tens of kilometers into the adjacent provinces forming a 100-km- (62 mi) wide zone of transitional tectonics, structure, and physiography.
