摘　　要：调查研究已表明，阿尔泰山发育有外生宝石矿床（点）．本文对它们的成因类型进行了划分，其中，古风化壳型；洪积-冰碛型；残积和残坡积型宝石矿床（点）、具有一定的远景，并着重描述了这几类矿床和典型实例，分别见到绿柱石类、电气石类和水晶类宝石．此类矿床（点）自然松散解离，宝石品质，含矿性均好于其原生矿床，易于开采，具有较好的找矿标志，应作为宝石矿床很有价值的类型，予以重视和开发．Recent research and investigation show that in Altay mountain of China, there are manyexogeneous gem-bearing ore deposits. Aceording to their genesis, they can be divided intofour groups and subdividedint eleven groups, Among them, the weathering orast deposit.pluvial-moraine deposit and residual concentration deposit have gemological value. The typ-ical deposits of them are discribed. Bering tourmaline and guartz are the mainly bearing per-cious stones. Because of loose and complete decay of its bearing rock, it may be consideredas an important and valuable new type gem-bearing ore deposit in this area.
