... Newly recognized cyclomedusoid fossils in the Antelope Mountain Quartzite confirm that it is latest Neoproterozoic (Ediacaran) in age. Biogeographic affinities of the cyclomedusoid fossils suggest that the Yreka subterrane and its close associate, the Trinity subterrane, formed after...

... The tectonic significance of early Paleozoic convergent-margin rocks of the Alexander and Sierran-Klamath terranes is poorly understood. New phengite 40 Ar/ 39 Ar and Rb-Sr results from the schist of Skookum Gulch of the Yreka subterrane in the Klamath Mountains (454 ± 10 Ma) confirm...

... in western Canada. Devonian strata of the Alexander terrane and Yreka subterrane (eastern Klamath terrane) have Caledonian and Baltican detrital zircon age signatures similar to Ellesmerian clastic wedge sandstones, implying that several Cordilleran terranes originated in the paleo-Arctic realm. Speculative...

... of the Trinity subterrane) and trench-slope deposits (Silurian-Devonian mélange and turbidities of Yreka subterrane). Trinity-Redding magmatic rocks are broadly cogenetic and were generated by partial melting of a depleted, residual MORB mantle source enriched by subduction-derived fluids ( Metcalf et al., 2000...

... the Mesozoic–Cenozoic Brookian fold-and-thrust belt. Recognition of a major pre-Mississippian unconformity within the fenster led to previous correlations between the Apoon assemblage and age-equivalent strata in the North Slope subterrane of the composite Arctic Alaska–Chukotka microplate. Previous age...

... incorporated into the accretionary complex. In the mélange, blocks of Ediacaran tonalite, as well as sandstones having detrital zircon populations with non–western Laurentian sources, may have been derived from the Yreka and Trinity terranes in the eastern Klamath Mountains, where similar rock types occur...
