Origin, development factors and dynamics of landslides in Jurassic clay in Moscow

The article focuses on the factors and dynamics of development of large deep extrusion landslides in Jurassic clay participating in geological structure of high bank slopes of the Moscow River within the city boundaries. The history of geological development of territory in Meso-Cenozoic age is observed in briefly; the peculiarities of upper Jurassic clay structure are considered; the structure, composition, and physico-chemical properties of rocks are described both in preserved and weathered state; the morphology and zoning of landslide slope structure as well as stages and dynamics of landslide deformations are characterized. Recommendations on the engineering development of territories affected by landslides are given. The paper is based on the generalization of numerous publications and archive data devoted to this acute topic.
