摘要
新疆阿勒泰区的额尔齐斯—玛因鄂博断裂带是划分阿尔泰褶皱区与北准噶尔褶皱区的一条重要构造结合带。南北两区,无论在地层、构造、喷发—侵入活动、矿化作用以及变质程度上均有明显不同,资料表明,它经历了长期的发育过程,最终发展成为两区的天然分界线。
In this paper, we have proposed that Irtys-Mayinebe fault is an important boundary to divide Altay fold region and north Junggar fold region, between which there is a distinctive difference in stratigraphy, structure, eruption-intrusion activity, mineralization, and mctamorphism. The data obtained indicate that Irtys-Mayincbc fault finally become the naturally boundary line between Altay and north Junggar fold region after long-term development process.
