The newlydiscovered Huangnikeng gold deposit is located in the GuangningLuoding fault zone, southern section of the Qinzhou-Hangzhou Metallogenic Belt (QHMB). In view of the research blank of this gold deposit, the petrography observation combining with SEM-EDS analysis are applied to obtain its mineral sequences. The wall rock of the Huangnikeng gold deposit is composed of the sandstone of the Cambrian Shuishi Formation with greenschist facies metamorphism including chloritization, sericitization and carbonation. The ore minerals consist of electrum, pyrite, arsenopyrite, sphalerite, galena, chalcopyrite, polybasite and molybdenite, etc., whilst the gangue minerals are dominated by quartz, chlorite, sericite, carbonate minerals, rutile, apatite, zircon, monazite, etc. Based on minerals cross-cutting relation and mineral assemblage, four main ore-forming stages are identified, including: ① the stage A of chloritizationsericitization；② the stage B of pyrite-arsenopyrite-polymetallic sulphides；③ the-stage C of pyrite-arsenopyrite-electrumc；④ the stage D of carbonatization. The most important economic mineral is electrum of the stage C distributed in particles and fractures of pyrites and arsenopyrites. The geological characteristics and mineral sequences of the Huangnikeng deposit are accordant to the global orogenictype gold deposits. Therefore, the Huangnikeng gold deposit can be considered as an example of orogenictype gold deposit in the southern section of QHMB.
