吐哈盆地南北两侧与盆地紧密相接的两座山脉分别是觉罗塔格山和北天山。许多研究者对北天山以及山脉与盆地北界的构造关系做了大量研究,并发表了相当多的论文和研究报告。但是针对觉罗塔格山与吐哈盆地构造关系的研究尚未见报导。本文通过野外地质调查结合地震剖面研究认识到: 1.觉罗塔格山从板块构造归属上应与北天山一样同属于东天山造山带,它们是塔里木板块的一部分; 2.觉罗塔格山与吐哈盆地的构造交接形式在不同地段表现不同,可以划分为三种构造类型: 1)托克逊冲断带型; 2)鄯善伸展构造型; 3)哈密和缓褶皱型; 3.觉罗塔格山、北天山与吐哈盆地所形成的盆地—山脉构造景观是新生代以来产生的。
吐哈盆地南北兩側與盆地緊密相接的兩座山脈分彆是覺囉塔格山和北天山。許多研究者對北天山以及山脈與盆地北界的構造關繫做瞭大量研究,併髮錶瞭相噹多的論文和研究報告。但是針對覺囉塔格山與吐哈盆地構造關繫的研究尚未見報導。本文通過野外地質調查結閤地震剖麵研究認識到: 1.覺囉塔格山從闆塊構造歸屬上應與北天山一樣同屬于東天山造山帶,它們是塔裏木闆塊的一部分; 2.覺囉塔格山與吐哈盆地的構造交接形式在不同地段錶現不同,可以劃分為三種構造類型: 1)託剋遜遲斷帶型; 2)鄯善伸展構造型; 3)哈密和緩褶皺型; 3.覺囉塔格山、北天山與吐哈盆地所形成的盆地—山脈構造景觀是新生代以來產生的。

North Tianshan mountain and Jiaoluotage mountain are located at the north and south of Tu- Ha basin respectively.A lot of scientific studies have been done on structural contact relationship between Tu- Ha basin and north Tianshan mountain.Many research papers have been published.But studies on structural contact types between Jiaoluotage mountain and Tu- Ha basin haven′ t been reported by now.By the field investigation and the analysis of seismic profiles we suggest that 1.Jiaoloutage is a part of eastern Tianshan orogenic belt as well as north Tianshan mountain.This area belongs to the Tarim active continental margin;2.three structural contact types have been found at the boundary between Jiaoluotage mountain and Tu- Ha basin.They are ① type of Tuokexun thrust belt;② type of Shanshan extensional structure and ③ type of Hami gentle fold;3.basin- mountain structure appears where both sides of a basin are mountains because of the collision of Indian and Eurasian plates.
