Postseismic deformation and the strength of ductile shear zones

Deformation path concepts in strain analysis: Applications for study of ductile shear zones

The internal fabric of a deformed rock represents the state of finite strain. In some special cases the fabrics also record the strain history of the deformed body. These special cases can profitably be utilized to compare the predictions of dynamic models and strain paths in natural deformations. In this contribution, the concept of deformation path in the study of ductile shear zones has been...

The distributions of slip rate and ductile deformation in a strike- slip shear zone

A simple mechanical model and dimensional analysis are used to derive a scaling law for the partitioning between slip rate on a strike-slip fault and distributed deformation in the far-field. The depth of the fault, the distributions of stress, strain rate and slip rate are solved for a given far-field force or displacement in a 2-D medium with a linear temperature-dependent viscous rheology. A...

Mechanics of low-angle extensional shear zones at the brittle-ductile transition

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

تحلیل ساختاری، خاستگاه و شرایط دگرشکلی زون‌های برشی شکل‌پذیر در توده‌ی گرانیتوئیدی ده نو- غرب مشهد

The Mashhad ophiolitic and metamorphic complex was intruded by Mashhad granitoids during different episodes of magmatisms. Dehnow pluton with diorite-granodiorite composition was intruded at earliest stage of magmatism during Late Triassic (Norian, 215± 4My). This pluton is cut by the NW-SE trending ductile shear zones which are dominated by an intense ductile deformation. The rocks of Dehnow p...
