Abstract: The Zaozigou gold deposit is located at the western part of the western Qinling Mountains in Gansu Province, and it is a super-large gold deposit discovered by regional geochemistry-national reconnaissance program in the 20th century. The deposit is a typical middle-low temperature magmatic hydrothermal deposit, and the orebody is mainly controlled by fault structures and dike rocks. In order to solve the Problem of deep prospecting, we were collected related data of 61 drillings and obtained 4 012 date of drimary halo in this paper. Through the correlation analysis, R-type cluster analysis, factor analysis, and zoning characteristics of primary halo, the best combination of indicator elements for gold prospecting is Au, As, Sb, Ag, Hg, W, while the closest and most direct indicator elements to gold mineralization are As and Sb. By calculating the index of primary halos, the axial zonation of this ore deposits is as follows (from high to low):Au-Hg-Bi-Pb-Mo-Sb-Ag-Cu-W-Zn-Co-As, and the reverse zoning phenomenon of the front elements (Sb, As) shows that blind ore bodies may exist in the deep. Base on the above studies and combined with geological knowledge, the ore-bearing potential and exact prospecting information in the deep were evaluated, the geological and geochemical deep prospecting model of the Zaozigou gold deposit was constructed, and finally two deep prospecting target areas were pointed out.

Key words: primary halo, zoning sequence, deep ore prediction, Zaozigou gold deposit, Gansu Province
