The concept of “Reworked Metallization” is a new theory proposed by Prof. Tu Guangzhi. This theory has its basic arguments and distinctive characteristics as follows: the extensiveness of metallogenic material; the uniqueness of ore-forming fluids; the activity of the metallogenic elements; the endogenic characteristic of the reworked metallization; the leading role played by faulting; the diversity of the host rocks; the wide- spreading of the reworked deposits.  Their metallization is unique and has a proper position in the four-fold division of ore deposits.  Dayao-Mouding type of sandstone-hosted copper deposits in Central Yunnan Province are of typical sedimentary-diagenetic- anadiagenetic-reworked metallogeneses.  The shape and occurrence of ore bodies, the texture and structure of ores, the behavior of ore-forming fluids and the source of water and the type of organic matter and its effect are distinct during different metallogenetic stages.
