准噶尔古生代地槽褶皱系,是中亚—蒙古地槽的一部分。一般认为它是由古生代时期介于西伯利亚地块与塔里木—中朝地块之间的海洋盆地演化而成,故属克拉通间地槽。然而关于它的基底性质、地槽性质、演化规律和俯冲→缝合→碰撞的构造运动,以及构造格局和超基性、中—酸性侵入岩的形成等重要问题尚缺乏深入研究,现在人们对其的认识还存在着重大分歧。笔者的认识是: The Junggar-Cenozoic geosyncline fold system is part of the Central Asia-Mongolia trench. Generally believed that it is from the Paleozoic period between Siberia and Tarim - China-North Korea terrane massif between the evolution of the sea, it is between the craton slot. However, there is a lack of deep research on the important issues such as the nature of its basement, the nature and evolution of the trough, the tectonic movement of the subduction → stitching → collision, as well as the tectonic framework and ultrabasicity, and the formation of medium-acidic intrusive rocks. There are still major differences in understanding. The author’s understanding is:
