摘要：

晚奥陶世与早志留世之间的都匀运动，使滇中古隆起与黔中古隆起成为一整体隆起带（习惯上称黔中古陆），把滇东南和黔南与滇东北—黔北—川南分隔为南、北两个不同的构造沉积域。南侧的曲靖一带出露下、中寒武统，其上分别与中、上志留统和下泥盆统呈假整合，其间缺失奥陶纪和早志留世的沉积物。北侧的禄劝－武定一带，下古生界的沉积序列与之相反，有完整的奥陶纪沉积组合，上与泥盆系假整合，其间无志留纪的沉积。这表明黔中古陆两侧的沉积域各为独立的系统。中晚志留世，黔中古隆起南侧应归属于上扬子与滇黔桂地块前陆挠曲盆地的一部分，由曲靖向北东经赫章哑都—贵阳南转向湘西，向南则与云南的绿春海相连，黔中古隆起北侧的沉积域则为上扬子前陆（川南—黔北）盆地的边缘相。

Abstract:

Duyun movement occurred between the late Ordovician and early Silurian, which resulted in an united uplift belt (commonly called Qian Zhong Oldland) from Dian Zhong uplift to Qian Zhong uplift. This uplift belt separated southeast Yunnan--south Guizhou region from northeast Yunnan--north Guizhou--south Sichuan region, which belong to two different depositional--tectonic domains, one in the south, and another in the north. In the south domain, lower and middle Cambrian, middle and upper Silurian, and lower Devonian series developed. There is an unconformity between the Cambrian and Silurian, and the Ordovician and Early Silurian are missing. On the contrary, in the Luquan --Wuding region of the  north domain, the Ordovician is complete, and is unconformably overlain by the Devonian, with the Silurian missing. The two different depositional sequences in north and south domains indicate that these two domains developed independently. In the middle--late Silurian, the area south of the Qian Zhong uplift should belong to  the Upper Yangtze Plate and the foreland flexural basin in Yunnan--Guizhou--Guangxi block. This area extended northeast from Qujing via Yadu of Hezhang--Guiyang to west Hunan, and southward linked with Huchun Sea in Yunnan. The area  north of the Qian Zhong uplift should belong to the marginal facies of the foreland basin (Sichuan south--Guizhou north) in the Upper Yangtze Plate.
