Upper Precambrian of the Middle Tien Shan
The article titled “Upper Precambrian of the Middle Tien Shan” describes the distribution and stratigraphic position of the sediments enclosing tillites and tilloids. Intraregional correlation of the sections was carried out.The great importance of Precambrian tillites and tilloids for interregional correlations has been noted. A division of the tillite-containing complex into two parts is proposed:1) Kichitaldysu and 2) Jetym. Upper Precambrian in the Talas-Karatau zone of the Northern Tien Shan and Karatau-Chatkal-Naryn zone of the Middle Tien-Shan were also correlated.
