新疆东部的库鲁克塔格、中天山和北山是我国西北地区前震旦纪地层的标准出露地点之一(图1)。1928年以来,E.(王那)琳和B.M.西尼村等曾先后对该区的前震旦系作过概略研究。1957年以后,地质部和新疆地质局的一些地质队曾到该区进行工作,搜集了较丰富的地质资料,为进一步研究本区前震旦纪地层创造了条件。笔者对上述地层及有关问题作了较系统的归纳和探讨,现简介于后,供读者参考。
Kuruktag, Junggar and Kitayama in the eastern part of Xinjiang are one of the standard exposing sites of the former Sinian strata in northwestern China (Figure 1). Since 1928, E. (Wang Na) Lin and B.M. Seni village have conducted a survey of the former Sinian in this area. After 1957, some geology teams from the Ministry of Geology and the Xinjiang Geological Bureau went to work in this area to collect more abundant geological data, which created the conditions for further studying the Pre-Sinian strata in this area. The author of the above strata and related issues made a more systematic induction and discussion, are briefly introduced for the reader’s reference.
