| 摘 要： | “黔中隆起”是南华纪一早古生代期间与南华裂谷造就的湘黔桂盆地演化有关的盆缘隆起。“黔中隆起”活动与盆地沉降曲线很好的吻合性证明了这点，二者是一对挠曲偶。这就是“黔中隆起”形成的地球动力学背景。伴随南华裂谷盆地的开合过程，“黔中隆起”经历了南华纪晚期雏形出现、震旦纪一奥陶纪水下发展、奥陶纪末期至早志留世古陆发展直到志留纪晚期的消亡。它不仅控制了当时该地区的古地理、古构造格局以及这段时期地层的垂直发育序列和横向分布、变化，而且对陡山沱组磷矿、石炭系九架炉组含铝岩系等形成分布、黔中地区后期岩浆活动及构造变形都产生着巨大影响。

| Abstract: | The upheaval in Central Guizhou, namely "Qianzhong Upheaval", is a basin-edge dome in relationship with the Xiangqiangui basin produced by the Nanhua rift valley during the Nanhuan Period to Lower Paleozoic. It is confirmed by the close accordance of the uplifting of "Qianzhong Upheaval" with the subsidence of the basin, that they are just a flexural pair, and this is the geodynamic background in the forming of Qianzhong upheaval. Accompanied with the opening-and-shutting process of the the Nanhua rift valley, the embryonic form of Qianzhong upheaval occurred in the Upper Nanhuan, developed subaqueously in the Sinian-Ordovician, and became an old land in late Ordovician to early Silurian, and dead in late Silurian. It not only controlled the paleogeographic and paleotectonic frameworks, the vertical and lateral variations of the strata then and there, but also made strong impacts upon the generation and distribution of the phosphorite of the Doushantuo Formation, the aluminum-bearing rocks of the Carboniferous Jiujialu Formation, and the later magmatic activities and tectonic deformation in central Guizhou. |
