摘要： 阿尔泰山构造地貌的基本特征不仅决定了砂金成因类型,也控制着砂金的沉积分布规律,在阿尔泰山不同走向的断裂交汇处往往形成断陷盆地、断陷谷地等负地形、或构成断块山结并发育有放射状水系,它们是对砂金富集成矿极为有利的地貌场所.

Abstract: This paper interprets the structural landform conditions of taking shape the placers in Altai Mountains. The basic feature of the structural landform not only control the placer's formations and types, but also control the deposit and distribution. The negative landform as tectonic basin and structural valley or mountain knot together with radiative river system were interlocked by the different alignment faults at their conjunction areas. They are the important landform to deposit placer gold.
