The newlydiscovered Huangnikeng gold deposit is located in the GuangningLuoding 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 chloritizationsericitization；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 orogenictype gold deposits. Therefore

the Huangnikeng gold deposit can be considered as an example of orogenictype gold deposit in the southern section of QHMB.
