关于震旦系在地质年表中的位置问题

震旦系在地质年表(地层柱)中的位置,自葛利普将其属于古生界作为第一个系之后,李四光首先明确地表示了他的不同意见。李氏认为:“在缺乏古生代化石的现实情况下,将震旦系归属于古生界,显然是不妥当的。”从此,震旦系属于古生界还是属于元古界就成悬案,各家有不同的见解。 1959年全国地层会议曾对震旦系隶属问题展开讨论,终沒有得到一致的认识。近几年来,国內外有关这一问题的讨论仍在不断地进行。我们一向是主张属于元古界的;这里愿意联系中国南方情况,再次较全面地申述这一观点。

POSITION OF THE SINIAN SYSTEM IN THE STRATIGRAPHIC COLUMN

On the basis of the fossil-record as well as the connexion between the tectonic movement and the history of organic evolution, the Sinian should be merely referred to cryptozoic. According to the age-interval, it is suitable to account the Sinian as a system of late proterozoic, but not to be an independent group. In view of the lithologic association and actual thickness, the same conclusion can also be reached.
