Abstract: The gold deposits of Algeria occur mainly in the Hoggar shield. Affected by the Pan-African movement, the gold deposits are distributed along north-south-trending fault belt. The Tin-Zakri deposit, which located in the north-south Tiririnienne metallogenic belt, is controlled by the NW-trending faults. Based on geological survey, 30 alteration zones with mineralizationaremapped,ofwhichtwometallization-alterationzones (Nos. 27 and 30) aremainorebodies.Theoccurrence of ore bodies are controlled by NW- and N-S-trending schistosity belts, and distributed in ductile shear zone as quartz veins. The sericitization is direct prospecting indicator, while the chloritization is important clue for gold mineralization.
