| Abstract: | Dayiaoshan area is one of famous gold mineralization belts, gold mineralization occurs regularly companied with decolourization, both resulted from a same origin, and relates closely to each other in space;decolourization is the last pro-duct of gold mineralization, and its scale is probably related to the extent of mineralization, it gives a remarkable instruction in land surface ore-prospect procession because of its special macroscopic scale, correct recognization of decolourization can promote the effect of ore-prospect. |

| Keywords: | decolourization effect of ore-prospect Dayiaoshan |
