Abstract
The mathematical methods and computers for stratigraphic correlation of Quaternary deposits have been applied, because on account of various reasons, this problem can't be completely solved using only methods of biostratigraphy and geochronology. The stratigraphic correlation of tills has been executed by using the results of lithological and geochemical investigations and mathematical-statistical methods. The application of the factor and cluster analysis have been most effective. Absolute data of the results of various laboratory investigations have been used for stratigraphic division of geological sections, while relative data (lithological and geochemical coefficients or pair correlation coefficients) have been used for stratigraphic correlation between the sections. Minimum number of samples necessary for statistic characteristics of each till has been obtained experimentally. Therefore the dependence of variation coefficient on the number of samples has been analyzed. The most reliable results of stratigraphic correlation of tills have been obtained using data of chemical (silicate) analysis.
