Abstract

The present work is based on the timing materials carried out by the staff of the All-Union Research Institute of Methods and Techniques of Exploration (VITRa) in the Karaganda coal basin and the Kustanay iron ore deposit. The structure of the deposit of the Dolinsk section of the Karaganda basin involves Quaternary, Tertiary and Paleozoic sediments. Quaternary sediments are represented by modern continental facies - mainly alluvium, deluvium and proluvium. The upper part of the Quaternary sediments consists of sandy loam, loam and multigrained sands with inclusion of pebbles. The thickness of sediments is from 7 to 15 l.
