As a result, 36 exceptional superlarge deposits ( peak mineral deposits) , 95 superlarge de- posits and 314 large deposits w ere selected as new cognition for their quantitative change. T he authors projected over 445 large-superlarge deposits on the ( 1B25 M) global tectonic background map and assigned them to 4 met- allogenic domains and 21 metallogenic belts. Global metallogeny of large-superlarge deposits includes unity of en- dogenic, exogenic metamorphic and epigenetic ore-forming processes in origin; speciality of different metallo- genic domains and belts; preferentiality of ore-forming elements of Cu, Au, Fe, Ag, Cr, Mn, Zn, Pb, Sb, Hg to continental margins or plate conver
