随着天山地区地质研究程度不断地提高,广大地质工作者给我国地质学的宝库积累了丰富的资料。当然,在大地构造学方面也增添了不少很有参考价值的内容。近年来,以尹赞勋教授为首的提出了天山旋回的概念,并建议以它作为中国晚古生代阶段的构造运动,从而取代长期统治我国构造地质领域的华里西(海西)旋回。继后,新疆地质局编写组和罗发祚分别发表了《中国天山地质构造特征》和《漫谈天山旋回》。为了使天山旋回更臻完善,笔者发表如下意见,以供读者参考。
As the degree of geological research in the Tianshan area continues to increase, the vast number of geological workers have accumulated a wealth of information for the treasure trove of geology in our country. Of course, in the tectonics also added a lot of very valuable content. In recent years, the concept of Tianshan cycle has been proposed by Professor Yin Zaixun and proposed to take it as the tectonic movement in the late Paleozoic stage in China, thus replacing the Hullisi (Hercynian) cycle which ruled the tectonic geology of our country for a long time. Following that, the writing team of Xinjiang Bureau of Geology and Luo Fazhuo published “Characteristics of Tectonic Structure in China’s Tianshan Mountains” and “Talking about Tianshan Cycle” respectively. In order to make Tianshan cycle more perfect, I make the following comments for readers reference.
