| Abstract: | Research on mineral geochemistry of copper\|gold deposits, Ertaizi, Zhenan County, Shaanxi Province, has shown that the copper\|gold exists in the albite\|carbonate brecciated rock series which were formed from Devonian to Yanshanian. Tennantite is rich in Fe, As and Cu and poor in Sb and Ag, with As ranging from \{17.84%\} to \{19.47%\}. Pyrite contains \{0.5%\} to \{4.5%\} As and 1.0% Se. Dolomite (inner core) is enclosed by Mn\|ankerite (outer part). (Mg\|Fe)\|rich feldspar occurs in the deposit. These are the mineral chemistry characteristics of the Ertaizi copper\|gold deposit. Mineral geochemical association types can be used to indicate the prospecting spots and mineralization types. Bancanggou near the Ertaizi copper\|gold deposit is the best target area for further exploration. |
