The Sullivan ore body, one of the world’s largest deposits of lead and zinc, is younger than a low-grade regional metamorphism of its host metasedimentary rocks but, on the basis of potassium-argon dating of a lamprophyre, is probably...

. Mixing between a mantle source and Belt Supergroup–like rocks appears to explain the variation seen in the alkalic and metaluminous suites, but the peraluminous suite requires an additional component. Another possibility is that an ancient mafic source comparable to the Mesoproterozoic Moyie sills, which
