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.
