The Cordilleran orogen of western Canada and Alaska records tectonic processes than
span over 1.8 billion years, from assembly of the Laurentian cratonic core of Ancestral North …

Paired belts of alkalic and calc-alkalic porphyry deposits are genetically linked to early
Mesozoic volcanic arcs preserved as the Quesnel and Stikine terranes in western Canada …

Serpentinization of ultramafic rocks drives geochemical exchange between the
hydrosphere, biosphere and lithosphere in surficial environments and at depth. Precious …

Abstract The Hazelton Group is a Rhaetian–Bajocian (uppermost Triassic–Middle Jurassic)
volcano-sedimentary sequence that represents both the last pre-accretionary arc volcanic …

There have been few studies of the green nephrite from Kutcho, northern British Columbia,
Canada. In this investigation, the petrology, mineralogy, geochemical characteristics, and …

Abstract The Late Triassic Guichon Creek batholith is host to the world-class Highland
Valley Cu-Mo porphyry system, comprising at least seven known mineralized centers …

Archean greenstone belts contain the oldest volcanic rocks on Earth and can provide critical
insights into Earth's early evolution. This study chooses the Sturgeon Lake greenstone belt …

In northwestern British Columbia, the Permian Nahlin ophiolite in the northern Cache Creek
terrane comprises spinel harzburgite tectonite with minor lherzolite, lower crustal mafic and …

Abstract The Squanga Lake ophiolite of southern Yukon exhibits a non-Penrose
pseudostratigraphy with mantle tectonites separated from upper crustal rocks by an …

The lithospheric mantle should be depleted in base-and precious-metals as these elements
are transferred to the crust during partial melting. However, some melt-depleted mantle …
