| 摘 要： | 阿尔及利亚金矿主要分布于南部地区Hoggar地盾.受泛非运动影响，Hoggar地盾与西非克拉通挤压碰撞，区内金矿沿南北向断裂带分布.Tin-Zakri金矿位于Hoggar地盾近南北向Tiririnienne成矿带上，受区内北西向主构造控制.目前发现与矿化有关的矿化蚀变带30条，其中规模较大的有2条（27、30号脉），矿体赋存在片理化岩带内，呈北西向或近南北向脉状展布，以石英脉的形式断续分布在韧性剪切带中.围岩蚀变特征明显，绢云母化为金矿的直接找矿标志，绿泥石化片理化带是金矿找矿的重要线索.

| 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. |
