Upper Paleozoic to Lower Jurassic oceanic rocks of the Cache Creek Terrane near Fort St. James, in central British Columbia, form a stack of thrust sheets cut by steeply dipping strike slip faults. Paleontologically dated upper Paleozoic strata include bioclastic shallow water limestone and ribbon chert. Isotopically dated Permian rocks consist of small tonalite intrusions and rhyolite flows in basalt flows. Paleontologically dated lower Mesozoic rocks include greywacke, sandstone, siltstone, argillite, ribbon chert, conglomerate, limestone and basalt tuff. Trembleur Ultramafic unit of the Cache Creek Group, in places a layer of an ophiolite suite, forms thrust sheets and klippe above lower Mesozoic sediments. Sedimentological, lithochemical, paleontological, petrological and textural comparisons with that of other areas and established models demonstrate the Cache Creek Terrane is a structurally stacked assemblage of diverse and disparate oceanic paleoenvironments. Represented environments include: spreading ridge, oceanic plateau, atoll, trench fill and possibly arc. Internal imbrication of the terrane is as young as Early Jurassic, and the minimum age of obduction of the thrust stack westward onto Stikine Terrane is Middle Jurassic. Triassic blueschist and eclogite of Cache Creek Terrane are interpreted to have been exposed by strike slip motion along the Pinchi Fault in the easternmost part of the terrane. Cache Creek Terrane is presumed to be overthrust from the east by the Triassic and Jurassic arc of Quesnel Terrane.
