摘要
一.引言 随着近年来地质勘测工作飞跃的发展,陆续发现了许多有关中国前寒武纪地层的新事实和新问题。1953年王曰伦等五台调查队著“五台山五台纪地层的新见”,认为:(i)五台系大部为滹沱系的花岗岩化变质部分;(ii)滹沱系底部为泳碛砾岩,其时代应属震旦纪。
In this paper,the stratigraphic position of the Huto and the Sinian systems is described.The Huto system was established by Willis and Blackwelder(1907)to denote the late Proterozoio formations lying between theirnamed palae ozoie Simian(Cambro-Ordovician)system and the older Proterozoica Wutai system.Grabau(1922)on the othe hand,considering the Huto system as the equivalent of his Simian system,re-defined the latter term so as to designate the first system of the Palaeozoic rocks well marked by an angular discordance at its base,but with no distinct discordance at its top.His opinion of referring the Sinian to the palaeozoic as its first system(Eo-Cambrian)though has not been unanimously accepted by the Chinese geologists,but the term of his sense has become the general and current use since his proposal.
