Qualitative and quantitative analysis of microstructures in Polish glacial tills with respect to their age

Abstract

A new method has been applied in the course of analysis of glacial tills, in areas glaciated during the North Polish, Middle Polish, and South Polish Glaciations. The method has not yet been commonly employed for assessing engineering-geological characteristics of soils. This study has allowed for determination that matrix microstructure is the most common in glacial tills. Among all tills in Poland the youngest tills have maximum porosity, but contacts and structural ties in these tills are loose. The older the glacial tills, the less porosity and closer contacts and ties they have.
