| 摘 要： | 出露于新疆西准噶尔托里老风口地区的晚古生代地层,岩性主要为火山碎屑岩,并含有丰富的腕足类、海百合茎等浅海相的生物化石。通过对其火山碎屑岩类岩石学特征、粒度分析数据和古生物化石的研究,表明新疆西准噶尔地区在晚志留世—早泥盆世到早石炭世期间沉积环境为滨海—浅海环境,同时为西准噶尔洋闭合时代的研究提供了沉积学依据。

| Abstract: | The late Paleozoic strata exposed in Lao Fengkou, Tuoli, Western Junggar is mainly pyroclastic rock, and rich in marine facies fossils such as Brachiopoda, crinoids stems, etc. Western Juggar had coast-shallow sea sediment environment from late Silurian-early Devonian to early Carboniferous by analyzing and studying on the characteristics and grading of pyroclastic rock and studying on fossils. In the meantime, the article also provides basic knowledge of sedimentology for the study on the closure of Western Juggar Sea. |
