Late Cenozoic uplift of the Eastern Cordillera, Bolivian Andes
This paper analyses Late Cenozoic uplift in the Bolivian Andes, using the morphology of well preserved regional paleosurfaces in the Eastern Cordillera that define three axially draining braided river catchments that formed between ∼12 and ∼9 Ma. Rock uplift since the formation of the paleodrainage systems, which has been quantified using four different methods, is 1705±695 m, with a mean erosi...
متن کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Effects of change in slab geometry on the mantle flow and slab fabric in Southern Peru
The effects of complex slab geometries on the surrounding mantle flow field are still poorly understood. Here we combine shear wave velocity structure with Rayleigh wave phase anisotropy to examine these effects in southern Peru, where the slab changes its geometry from steep to flat. To the south, where the slab subducts steeply, we find trench-parallel anisotropy beneath the active volcanic a...
متن کاملMantle plume influence on the Neogene uplift and extension of the U.S. western Cordillera?
Despite its highly extended and thinned crust, much of the western Cordillera in the United States is elevated over 1 km above sea level. Thus this region cannot be thought of as thick crust floating in a uniform mantle isostatically; rather, the lithospheric mantle and/or the upper asthenosphere must vary in thickness or density across the region. Utilizing crustal thickness and density constr...
متن کاملSlab breakoff A model for syncollisional magmatism and tectonics in the Alps
Slab breakoff is the buoyancy-driven detachment of subducted oceanic lithosphere from the light continental lithosphere that follows it during continental collision. In a recent paper Davies and von Blanckenburg [1994] have assessed the physical conditions leading to breakoff by quantitative thermomechanical modeling and have predicted various consequences in the evolution of mountain belts. Br...
