基于地层学和古生物学的研究,论及奥陶纪中国华南、华北和塔里木3个块体中发生的构造事件.华北和塔里木地台区内及其边缘带在晚奥陶世凯迪期有一次区域性的抬升事件,表现为这些地区的奥陶系与其上覆的晚古生代地层间的假整合接触.陕西陇县和耀县的笔石和牙形刺新资料表明,那里的奥陶系最高层位为笔石Diplacanthograptus spiniferus带(凯迪阶下部).而塔里木地台区的奥陶系最高层位也与之相当,但其边缘带略高一些,相当于笔石Dicellograptus complanatus带.华北和塔里木区域性构造抬升事件都发生在凯迪早期,只是塔里木的抬升持续时间较短.这一构造抬升与中国东南部广西运动的起始时间一致.广西运动提出后在我国曾长期被加里东运动一名所取代,但二者在地理分布、构造性质和活动时限上均不同,建议使用“广西运动”名称,而不宜在华南、华北和塔里木再使用“加里东运动”一名.
Based on the study of stratigraphy and paleontology, the paper deals with the tectonic events occurring in the Ordovician blocks in South China, North China and Tarim.Throughout the Late Ordovician Kaidi Period in the North China and Tarim platforms, The regional uplift shows the fake contact between the Ordovician and its overlying Late Paleozoic strata in these areas.The new data of petroglyphs and conodonts in Long County and Yao County of Shaanxi Province show that there is the highest Ordovician While the uppermost member of the Ordovician in the Tarim platform area is also comparable with the slightly higher margin, which is equivalent to the Dicellograptus complanatus belt in the Tarim Basin. The North China and Tarim The regional tectonic uplift occurred in the early period of Kaidi, but the uplift of Tarim lasted for a short time.The tectonic uplift coincided with the start of the Guangxi movement in southeastern China.After Guangxi movement was proposed in our country for a long time by a Caledonian movement However, the two are different in terms of geographical distribution, nature of construction and duration of activities. It is suggested that the name of “Guangxi Movement” should be used instead of the name of “Guangxi Movement” rather than the name of “Guangxi Campaign” in South China, North China and Tarim “Caledonian ” said one.
