ANALYSIS ON DEEP SOURCE-ISOSPACE-MULTIPERIODS METALLOGENESIS OF LARGE SCALE COPPER DEPOSITS AROUND THE WESTERN MARGIN OF YANGTZE PLATFORM IN CHINA

摘要

Deep source, isospace, multiperiods metallogenesis is an important metallogenic mechainsm of many large-scale, rich ore-deposit and prospective mineralization concentrated areas in China, especially in western margin of yangtze platform. Among others the mineralization characteristics of Dongchuan, Sanjiachang, Dahongshan copper deposits in Yunnan Province and Tongchang copper deposit in Shenxi Province, which are closely correlated with the above metallogenic mechanism, were investigated respectively.
