Summary

Results of extensive investigations carried out by the authors on the microstructures of genetic types of clay soils differing in composition, age and degree of compaction are presented. Clays of marine, lacustrine, alluvial, glacial, glacial-lacustrine and eluvial origin have been studied. Investigations were carried out with the help of scanning electron microscopy and the X-ray method. The data obtained have made it possible to ascertain that each genetic type of clay-soil has its characteristic microstructure, which confirms the close interrelation of the microfabric of clay sediments with the conditions of their formation and their subsequent transformation in the course of compaction.

Relation Entre La Microstructure Des Roches Argileuses, Leur Genese Et Leur Degré De Compaction

Résumé

Les auteurs présentent les résultats de plusieurs années de recherches concernant les microstructures de roches argileuses de divers types génétiques différant par leur composition, leur âge et leur degré de compaction. Des argiles d’origine marine, lacustre, alluviale, glaciaire, lacustro-glaciaire et éluviale ont été étudiées. Les recherches furent réalisées à l’aide du microscope électronique à balayage et par la méthode des rayons X. Les données obtenues ont permis d’établir qu’à chaque type génétique de roches argileuses correspondent des particularités défines de leurs microstructures ce qui confirme une corrélation étroite de la microstructure des sédiments argileux avec les conditions de leur formation et de leur transformation ultérieure au cours de leur compaction.
