Modes of extensional faulting controlled by surface processes

Modes of extensional faulting controlled by surface processes

We investigate the feedbacks between surface processes and tectonics in an extensional setting by coupling a 2-D geodynamical model with a landscape evolution law. Focusing on the evolution of a single normal fault, we show that surface processes significantly enhance the amount of horizontal extension a fault can accommodate before being abandoned in favor of a new fault. In simulations with v...

Post-Triassic normal faulting and extensional structures in Central Alborz, Northern Iran

This paper presents structural evidence of extensional activity in Central Alborz during Mesozoic. The structural evidence of homogenous early stage stretching such as layer-parallel to oblique boudinage of Permian and Triassic rocks in various portions of the study area accompanied by extensional-fibrous fractures were followed with more advanced extensional features. These extensional structu...

An Extensional Spatial Logic for Mobile Processes

Existing spatial logics for concurrency are intensional, in the sense that they induce an equivalence that coincides with structural congruence. In this work, we study a contextual spatial logic for the πcalculus, which lacks the spatial operators to observe emptyness, parallel composition and restriction, and only has composition adjunct and hiding. We show that the induced logical equivalence...

Extensional flow of low-viscosity fluids in capillary bridges formed by pulsed surface acoustic wave jetting

Forming capillary bridges of low-viscosity (.10mPa s) fluids is difficult, making the study of their capillary-thinning behavior and the measurement of the fluid’s extensional viscosity difficult as well. Current techniques require some time to form a liquid bridge from the stretching of a droplet. Rapidly stretching a liquid bridge using these methods can cause its breakup if the viscosity is ...
