Talc-kyanite-quartz schists and other high-pressure assemblages from Zambia

Abstract

Summary Talc-kyanite-quartz schists, Mg-chlorite-kyanite-quartz schists, kyanite gedritites, and kyanite-bronzite gedritites occur in the Central Province of Zambia. Experimental work in the system MgO-Al 2 O 3 -SiO 2 -H 2 O suggests that these assemblages formed at pressures in excess of 10 kb.
