西伯利亚乌楚尔—马亚区上前寒武系剖面在苏联境内是一个比较典型的里菲系层型剖面,闸明此剖面中核形石的垂向分布情况,对于上前寒武系地层的划分和对比意义很大。乌楚尔—马亚区上前寒武系地层研究较早,发表的文章也较多。先后有德泽瓦诺夫(1939.1943.1946),亚尔莫留克(1946.1956),C.B.努日诺夫(1967)等人对乌楚尔—马亚地区上前寒武系进行了划分。最近又有阿尔丹地质队(1965)科马
The Upper Precambrian section in the Uzul-Maya region of Siberia is a relatively typical Lefi-type stratigraphic section in the Soviet Union that indicates the vertical distribution of the nuclei in this section. For the Upper Precambrian strata Divide and contrast is of great significance. The Uzul-Maia region studied earlier the Precambrian strata and published more articles. There are De Prevanov (1939.1943.1946), Almourouk (1946.1956), C. B. Nurov (1967) and others on the Uzul-Maya region, the Precambrian division. More recently, the Arden Geological Team (1965) Cooma
