Basin and Range–Colorado Plateau transition

E842017

geologic boundary zone tectonic transition zone

The Basin and Range–Colorado Plateau transition is a geologic boundary zone in the southwestern United States where the highly extended Basin and Range Province meets the relatively stable, uplifted Colorado Plateau, producing complex faulting, volcanism, and varied topography.

How this entity was disambiguated

This entity first appeared as the object of triple T10107324 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

A. Wyoming Basin and Range transition
The Wyoming Basin and Range transition is a geologic province in western Wyoming marking the structural and topographic boundary between the high, rugged ranges of the Rocky Mountains and the more subdued basins and ranges to the west and south.
B. Colorado Plateau transition zone
The Colorado Plateau transition zone is a geologic and ecological boundary region in the southwestern United States where the high, stable Colorado Plateau gives way to lower, more tectonically active provinces, creating diverse landscapes and habitats.
C. Basin and Range Province
The Basin and Range Province is a vast geologic region of the western United States and northern Mexico characterized by alternating mountain ranges and arid basins formed through crustal extension.
D. Great Basin–Southwest transition zone
The Great Basin–Southwest transition zone is a culturally and ecologically diverse border region between the Great Basin and American Southwest, characterized by overlapping Indigenous territories, mixed desert and plateau landscapes, and hybrid cultural traditions.
E. Great Basin–Mojave transition zone
The Great Basin–Mojave transition zone is an ecologically and culturally significant desert region in the American Southwest where the Great Basin and Mojave deserts meet, characterized by mixed flora, fauna, and long-standing Indigenous presence.
