Ursachen und Mechanismen des Trocknungs-Befeuchtungs-Zerfalls überkonsolidierter Peliteontact between the clay particles is weakened by desiccation and the structure collapses when rewetted..The extent of the initial increase in strength depends on the degree of clay particle orientation. The preferred orientation is independent of the rate of diagenesis..The decrease in strength by r

Einfluß organischer Substanzen auf die verwitterungsbedingte Entfestigung von Peliten am Beispiel dee of the Posidonia Shales. It is usually possible to reach almost unweathered bedrock at a depth of around 1 to 2 meters below ground surface. A distinct dependence of rock strength on organic content has been proven by uni-axial compression tests (fig. 4).
