本文是我们调查全球主要晚前寒武纪岩石组合(建造组)的主要类型的工作成果,采用了过去对古生代、中生代和新生代岩石的分析方法,根据以前惯用的出版原则编制世界岩石组合图(建造图)。我们的三篇文章将依次探讨晚前寒武纪(早、中、晚里菲和文德)的地层划分。晚前寒武纪的古地理和沉积作用与显生宙比较更复杂,因为晚元古代时间延续长,地层划分争论大,用做全面对比的原始地质资料不足,特别是对地槽带的对比较难,因其原岩多已变质了。
This paper is the result of our survey of the major types of major late Precambrian rock assemblages in the world, using the methods used to analyze Paleozoic, Mesozoic and Cenozoic rocks in the past and compiling the World Rock Combinations according to previously published principles (Construction plan). Our three articles will in turn explore the stratigraphic division of the late Precambrian (early, middle and late Philippine and Wende). The paleogeography and sedimentation of the late Precambrian are more complicated than that of the Phanerozoic because the late Proterozoic lasted for a long time and the stratigraphic division was controversial. The original geological data for comprehensive comparison were not sufficient, especially for the geosyncline More difficult, because the original rock has more than deterioration.
