ABSTRACT The North American Cordillera experienced significant and varied tectonism
during the Triassic to Paleogene time interval. Herein, we highlight selected questions and …

The Fossil Bluff Group of eastern Alexander Island records the exceptional preservation of
more than 8 km of Mesozoic sedimentary rocks deposited into an accretionary forearc basin …

Detrital zircon U-Pb studies of mudstone provenance are rare but may preferentially
fingerprint distal zircon sources. To examine this issue, Pierre Shale and Trinidad …

Basin analysis and tectonic reconstructions of the Cenozoic history of the Death Valley
region, California, USA, are hindered by a lack of volcanic (tuff) age control in many …

The Earth is the only known planet where plate tectonics operates. We review the features of
Archean and early Proterozoic geology that constrain tectonic environments and inform …

The Laramide foreland belt comprises a broad region of thick-skinned, contractional
deformation characterized by an anastomosing network of basement-cored arches and …

Abstract The Upper Cretaceous Frontier Formation in southwestern Montana is coeval with
the transition from Sevier‐to Laramide‐style tectonism in the Idaho‐Montana sector of the …

Detrital zircon (DZ) geochronology is based on a multistage, hierarchical sampling process
in which sampling errors (statistical variance) and non-sampling errors (sampling bias) are …

Downstream sediment transport in river systems is impacted by anthropogenic
modifications, such as dams or levees. This study used detrital zircon U-Pb geochronology …

Abstract Development and evaluation of models for tectonic evolution in the Cascadia
forearc require understanding of along-strike heterogeneity of strain distribution, uplift, and …
