Stress-State and Sliding Between Colliding Plates in the Subduction ZonePages 1-7
Emilia Assenova Abstract:
Understanding of friction is important for tribological processes ranging from
engineering contact systems to the nonmechanical inorganic tribosystems of
Earth’s seismo-tectonic zones. A common but little-studied case is the
combination of interaction, sliding and counter-pressure (collision) between
plates and rock blocks, which develops specific deformations and energy and
material changes. Above friction processes depend on the geometry, the
spatial relations between the crustal plates, their material, especially
rheological properties, and the energy transformations. The subduction zone
has been regarded as place of renewal processes of energy and material. The
role of the intensive friction processes in the increase of temperature and
pressure in the subduction zone is shown, and the resulting both internal,
external deformations and material changes of the rock material. A
hypothesis is presented for the formation of the so-called "Deformation Arc"
observed in the Alps, the Chilean segment of the Andes and the Nepalese zone.
A contribution to science represents the application of tribological principles
in the interpretation of natural, in this case geotribological processes, which
leads to mutual enrichment of both tribology and geology Keywords: Friction,
