Abstract

Clayey silts involved in a landslide have been sampled to study the role of sediment composition in developing sliding surfaces. Five drillings enabled the collection of 46 samples and to define active slide surfaces and non-active surfaces (discontinuities). Results and discussion about the granulometrical, chemical and mineralogical data. Scanning electron microscopy demonstrated that active slide surfaces have an open texture, clay minerals are impoverished and non-oriented, whereas secondary phases (hematite and gypsum) are enriched. There is a relationship between geotechnical features and mineralogical composition
