摘要
本文简要评述了新疆地区前震旦纪构造格局、古生代洋盆打开与闭合的时限、北疆晚古生代岩浆活动的构造背景与成因机制、新疆侏罗纪以来的陆内地壳演化、以及新疆地壳现今结构及其形成与演化的动力学机制等问题 ,并且提出了一些新的见解。
Based on recent field and in-door researches and investigations, this paper briefly statesand reviews on some issues on the crustal framework and tectonic evolution such as the pre-Sinian tectonic framework, opening and closing ages of the Paleozoic ocean, tectonic settings and originations of the Late Paleozoic magmatism in northern Xinjiang, crustal evolution of Xinjiang since the Jurassic, and dynamics of formation and evolution of Xinjiang crust.
