原来认为阿尔泰地区的大地构造位置属北疆地洼区北缘。后来研究证明,本地区与北疆地洼区的其它广大地区的地质特征有很大差别。地质发展历史表明本区进入地洼阶段较早,是北疆唯一的燕山期花岗岩比较发育的地区,属华夏期地,洼而北疆其它地区属中亚期(型) Originally believed that the Altai area is located in the northern tectonic structure of the northern depression depression area. Later studies show that there are great differences between the geological features of this area and other vast areas in the depression area of ​​northern Xinjiang. The history of geological development shows that the area entered the Diwa stage earlier and is the only area with relatively developed Yanshanian granite in northern Xinjiang, belonging to the Huaxia period and depression, while the rest of the northern area belongs to the Middle Asia (type)
