The Kootenay Arc has been interpreted as the western limit of autochthonous continental margin strata, west of which occur Paleozoic to Mesozoic rocks of uncertain paleogeographic origin. Recent mapping has demonstrated stratigraphic linkage between

Detailed geological mapping across the Shuswap metamorphic complex between latitudes 50°00′N and 50°45′N reveals that superstructure forms a semicontinuous carapace across the complex, with minimal evidence of internal thinning. Near the wester

The Aberdeen gneiss complex is composed of complexly deformed migmatitic orthogneiss and paragneiss situated within the core of the Vernon antiform, a structure defined by a series of subparallel reflectors visible at upper to middle crustal depths (

A Paleozoic volcanic assemblage exposed in northern British Columbia, near the Turnagain River, previously considered to be part of an accreted terrane, was reported to be in depositional contact with a part of the Cordilleran miogeocline. This paper

The Lithoprobe Slave Northern Cordillera Lithospheric Evolution (SNORCLE) study across northwestern North America, in combination with related crustal studies, has been synthesized into an 1800 km long cross section of the lithosphere that is cons

The Nicola horst exposes plutonic and amphibolite-grade metamorphic rocks and is surrounded by low-grade arc rocks of the Late Triassic Nicola Group. We present new geological mapping and UPb, Nd, and metamorphic data for the Nicola horst near Bob

The Long Range Mountains of Newfoundland expose the northeastern most basement inlier of the Appalachian Orogen. UPb results for two samples of basement gneiss reveal crustal formation ages of 1466 ± 10 Ma (Western Brook Pond charnockite) and 1530

The Apuseni Mountains in Romania expose pre‐Alpine crustal basement rocks between the Carpathian and Dinaride segments of the Alpine Orogen. Because of a lack of direct constraints, the age and plate affinity of the basement rocks have been largely

New geochemical and Nd isotopic data from Triassic (ca. 220 Ma) clastic metasedimentary rocks assigned to the Quesnel terrane (Quesnellia) in southeastern British Columbia show that detritus was derived from both primitive and evolved sources. Twenty
