Abstract This paper proves that Beishan area belongs to Tarim plate north margin, and discusses evolutionary series of geological tectonics. Beishan area can be divided into three belt; north belt, intermediate belt, south belt. It can be divided in to four stages; forming ancient continental crust in Precambrian,island arc and rifting -closure within continental margin in Caledonian, tectono-magmatic activation succeeding as arc and second rifting-closure in Her-cynides, and fault block disparity elevator in Mesozoic-Cenozoic.
