摘　　要：贵州梵净山区有保存完好、发育齐全的中元古代的地质记录 ,是扬子陆块晚前寒武地质研究的理想场所和重要窗口。现有地质和同位素年代学等资料表明 ,该区存在格林威尔期造山带 ,其形成时间为ca 10 0 0Ma±。它同原始江南造山带一起成为华南Rodinia超大陆的组成部分 ;对其进行探讨 ,必将促进我国Rodinia超大陆聚合、裂解及其演化的研究 ,并具有重大的科学意义。There occur well-reserved and typical and complete geologic records of the mesoproterozoic in the Fanjing mountain area of Guizhou, where is a valuable place and window for the sake of studying the Yangtze block of the late Precambrian. Still available data in geology and isotope geochronology show that in the area arises the orogenic belt of the Grenville-age shaped in ca.1000Ma± approximately. With original Jiangnan orogenic belt, both of them become parts of the Rodinia supercontinent in southern China. This working will deeply promote the study on the convergent, breakup and evolution of the Rodinia supercontinent in China, is of greatly scientific significance.
