| Abstract: | The Huachanggou gold deposit is located in the favorable ore\|forming sectors of the Mian\|Lue\|Ning triangular area. There are Middle\|Lower Devonian Sanhuokou Group and Middle\|Upper Proterozoic Bikou Group in the ore district. The ductile shear zones which underwent multiple activities from right\|handed (ductile) to left\|handed (ductile\|brittle) and right\|handed (brittle) movement are developed in the gold deposit. The mineralized zone is controlled by some spilite lens distributed in the ductile shear zone. Orebodies have been intensely altered, and new minerals are orientationally arranged. Characteristics of plastic deformation of stress minerals in veins, such as subgrain tectonics, deformation, lamellae and deformation bands, can be found. Isotopic analyses and REE patterns indicate that the basic volcanic rock is the gold source bed. The altered calcic mylonitic and silicified quartz coarse mylonitic gold ores can be found in addition to the altered spilite gold ores in the ductile\|brittle ore\|controlling shear zones of this deposit. |
