Alkalic Igneous Rocks on the Continents,mpared to silica-saturated granitic rocks. They are also characterized by high abundances of relatively rare elements including P, F, CI, Zr, Ti, Nb, Ta, and REEs. Alkali-rich plutons tend to be elliptical or circular in plan and are smaller in volume than plutons of granitic rocks. They are compose

Archean Greenstone Belts and Granitic Gneisses of North America,led greenstone belts are the remnants of large volcano-sedimentary complexes of Archean and Proterozoic age. The volcanic rocks range in composition from komatiites and low-K tholeiites to dacites and rhyolites and consist of lava flows, sills, and stratified tuffs. The sedimentary rocks are typical
