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 models invoke low-angle subduction2–4, which can develop for various reasons5,6. Evidence from South America indicates that one such reason may be the subduction of buoyant ocean floor. We here extend the low-angle subduction models by attributing the shallowing of the subduction angle during the… 

The Laramide Orogeny: What Were the Driving Forces?

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

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

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

Laramide Orogenesis Driven by Late Cretaceous Weakening of the North American Lithosphere

This paper investigates the causes of the Late Cretaceous transition from “Sevier” to “Laramide” orogenesis and the spatial and temporal evolution of effective elastic thickness (EET) of the North

Nazca–South America interactions and the late Eocene–late Oligocene flat‐slab episode in the central Andes

The most prominent features of the Andean range are the Altiplano and Puna plateaus, which were constructed by crustal shortening and uplift over the past ∼45 Myr. The early construction of these

Paleomagnetic dating of fault slip in the Southern Rocky Mountains, USA, and its importance to an integrated Laramide foreland strain field

The Laramide orogen of the U.S. Cordillera formed in the latest Cretaceous, and deformation lasted into the earliest Oligocene. Along and proximal to the eastern and northern margins of the Colorado

Franciscan Complex Calera limestones: accreted remnants of Farallon Plate oceanic plateaus

The Calera Limestone, part of the Franciscan Complex of northern California, may have formed in a palaeoenvironment similar to Hess and Shatsky Rises of the present north-west Pacific1. We report

Early Inception of the Laramide Orogeny in Southwestern Montana and Northern Wyoming: Implications for Models of Flat‐Slab Subduction

Timing and distribution of magmatism, deformation, exhumation, and basin development have been used to reconstruct the history of Laramide flat‐slab subduction under North America during Late



Observations of flexure and the geological evolution of the Pacific Ocean basin

The response of the Pacific plate to oceanic island and seamount loads has been used to estimate the distribution of ridge crest and off-ridge volcanism on the plate since the late Jurassic. The most

Magmatism, orogenic timing, and orogenic diachronism in the Cordillera from Mexico to Canada

The distinction between the largely intra-Cretaceous Sevier orogeny and largely post-Cretaceous Laramide orogeny in the Cordillera between Montana and New Mexico does not exist in the northern Rocky

Volcanic rocks cored on Hess Rise, western Pacific Ocean

Large aseismic rises and plateaus in the western Pacific include the Ontong–Java Plateau, Magellan Rise, Shatsky Rise, Mid-Pacific Mountains, and Hess Rise. These are relatively old features that

Cordilleran Benioff zones

Ages of late Mesozoic–early Cainozoic igneous rocks in south-western North America indicate a magmatic arc initiated near the continental margin, swept over 1,000 km northeastward, then swept back,

Upraised Pacific Ocean floor, southern Malaita, Solomon Islands

Oceanic tholeiitic basalt flows of probable Early Cretaceous age form the basement rocks exposed in the southern half of Malaita and also on adjacent Small Malaita in the Solomon Islands. In the

Compression and crustal shortening in Andean-type orogenesis

CONTROVERSY exists as to the role of crustal compression and shortening in the formation of the easterly-directed thrust system in eastern portions of the North American Cordilleran orogen1,2. In

Paleogene Sediment Dispersal and Paleotectonics in Northern California

The Paleogene tectonic setting of California remains uncertain even though the general nature of earlier and later events is now understood. Cretaceous subduction (Hamilton, 1969) gave rise to a

Buoyant ocean floor and the evolution of the Caribbean

Ocean floor in the Caribbean was formed mainly during the Jurassic and Cretaceous. Subduction of the young Caribbean ocean floor started by Late Jurassic times and persisted until the Eocene on its
