【Abstract】 diagenetic ore-forming process is of important for stratabound ore deposits. It include diagenetic differentition, diagenetic replacement, autgenesis, dehydration, sluicing, compaction, compression, diffusion and cemetation. As a result in the primary sediments remobilization, migratationand enrechment take place, at the same time the distinctive features of fabrics such as slaty, vein, zonal and nodular texture-structure are formed. The paper is based on study of the Makeng type Iron deposits and the Copper deposits in the Lower-Middle Yangtze area, deals with diagenetic ore-forming process and material migration process, as well as forming mechanism.更多还原
