The Laramide orogeny is the Late Cretaceous to Paleocene (80 to 55 Ma) orogenic event that gave rise to the Laramide block uplifts in the United States, the Rocky Mountain fold-and-thrust belt in Canada and the United States, and the Sierra Madre Oriental fold-and-thrust belt in east-central Mexico. The Laramide orogeny is believed to post-date the Jurassic and late Early Cretaceous accretion of the terranes that make up much of the North American Cordillera, precluding a collisional origin for… 
Hydrodynamic mechanism for the Laramide orogeny
The widespread presumption that the Farallon plate subducted along the base of North American lithosphere under most of the western United States and ∼1000 km inboard from the trench has dominated
Evidence for two Cretaceous superposed orogenic belts in central Mexico based on paleontologic and K-Ar geochronologic data from the Sierra de los Cuarzos
The continental interior of Mexico is characterized by a Late Cretaceous–Eocene fold-thrust belt named the Mexican Fold-Thrust Belt, which shows characteristics of an eastward-tapering orogenic
Límites temporales de la deformación por acortamiento Laramide en el centro de México
In central and northern Mexico, sets of rocks deformed by shortening between the Late Cretaceous and early Cenozoic have been considered the result of the Laramide orogeny. This orogeny is mentioned
The Cordilleran Ribbon Continent of North America
The North American Cordilleran Orogen is the result of a two-stage process: (a) Triassic-Jurassic accretion within Panthalassa forming SAYBIA, a composite ribbon continent, and (b) Late Cretaceous
Location, location, location: The variable lifespan of the Laramide orogeny
The Laramide orogeny had a spatially variable lifespan, which we explain using a geodynamic model that incorporates onset and demise of flat-slab subduction. Laramide shortening and attendant uplift
Morphotectonic and Orogenic Development of the Northern Andes of Colombia: A Low-Temperature Thermochronology Perspective
Landscapes in mountain belts evolve through complex feedback mechanisms between internal and external processes. Modern orogenic belts, such as the Andes, are the result of millions of years of
The role of oceanic plateau subduction in the Laramide orogeny
The cause of the Laramide phase of mountain building remains uncertain. Conceptual models implicate the subduction of either ocean ridges or conjugates of the buoyant Hess or Shatsky oceanic


Was the Laramide orogeny related to subduction of an oceanic plateau?
Numerous models have been presented to explain the late Cretaceous/early Cenozoic Laramide orogeny, which affected the foreland region of the western cordillera within the US1. The most attractive
Tectonic accretion and the origin of the two major metamorphic and plutonic welts in the Canadian Cordillera
The Omineca Crystalline Belt and Coast Plutonic Complex are the two major regional tectonic welts in the Canadian Cordillera in which were concentrated intense deformation, regional metamorphism,
The big flush: paleomagnetic signature of a 70 Ma regional hydrothermal event in displaced rocks of the northern Canadian Cordillera
The 70 Ma Carmacks Group, a subaerial volcanic succession which once covered much of central southwest Yukon, has a paleomagnetic remanent direction which passes the fold test and the reversal test.

Summary The thick (∼40 km) slab of Hudsonian (>1750 Ma) continental crust that extends under western Canada from the Canadian Shield can be followed westward, on the basis of its distinctive magnetic
Segmentation of the Laramide Slab—evidence from the southern Sierra Nevada region
During the latest Cretaceous-early Paleogene Laramide orogeny, the lithosphere beneath the southernmost Sierra Nevada batholith and the adjacent Mojave Desert region batholith was sheared off and

Carboniferous to Cretaceous assembly and fragmentation of Mexico
The geologic framework of Mexico evolved through the Phanerozoic assembly and fragmentation of crustal elements derived from Laurentia, Gondwana, and an intra-Pacific volcanogenic terrane. In middle
Yakutat collision and strain transfer across the northern Canadian Cordillera
The collision of the Yakutat block in the corner of the Gulf of Alaska has resulted in large deformation in the adjacent Chugach‐Saint Elias Mountains. This collision is inferred to produce the
