西起大卡拉套山脉,东迄中国库鲁克塔格,出露大片古老(前泥盆纪)岩层,构成一个延伸极长(2000公里)的狭长岩带,我们早就论述过它们同属于—构造岩相杂岩带。就现在的构造分区来看,该带属于中天山查特卡尔—纳伦带。该杂岩分为两个部份。上部的岩层时代业经(化石)证明是奥陶纪和中—晚寒武世的。下部为哑层,其时代有争议:有些调查者认为是早—中寒武世,另一些调查者则认为是晚前寒武纪。杂岩的下部(见图1)包括通常称之为“似冰碛砾岩”未经分选的特殊碎屑岩层,系
From the Great Kalatao Mountains in the west to the Kuruktag in the east of China, the vast ancient (Pre-Devonian) rock formations are exposed to form an extremely long (2000 km) long strip of rock that we have already discussed - Constructing lithofacies complexes. Judging from the present tectonic zoning, the belt belongs to the Zotkar-Naryn belt of the Tianshan Mountain. The complex is divided into two parts. The Upper Paleolithic provenance (fossil) proved to be Ordovician and Middle-Late Cambrian. The lower part is dumb, and its age is controversial: some investigators think it is Early-Middle Cambrian, while others think it is Late Pre-Cambrian. The lower part of the complex (see Figure 1) consists of an unspecified special clastic formation, commonly referred to as “moraine conglomerate”
