Landslides Related to Occurrence and Transport Mechanism of Clay Minerals

Abstract

Geographical and geological features as the primary cause and intense precipitation as the trigger are related to landslides. The most important factor is the occurrence of clay minerals. Clay minerals are observed in clay vein and micro- crack, are generally developed in granite. Specifically, smectite expands or swells in wet conditions, and is important as the material sharing the responsibility of landslides. To elucidate mechanisms by which landslides occur, an understandings of heterogeneity of sediments and/or rocks is needed.
