Large-scale deformation associated with ridge subduction

Large - scale deformation associated with ridge subduction

S U M M A R Y Continuum models are used to investigate the large-scale deformation associated with the subduction of aseismic ridges. Formulated in the horizontal plane using thin viscous sheet theory, these models measure the horizontal transmission of stress through the arc lithosphere accompanying ridge subduction. Modelling was used to compare the Tonga arc and Louisville ridge collision wi...

The Role of Deformation in the Formation of Metamorphic Gradients: Ridge Subduction beneath the Oman Ophiolite

Two tectonic scenarios have been proposed for genesis and emplacement of the Oman ophiolite. One suggests that the ophiolite was generated at a spreading center, the other suggests generation within an intraoceanic arc. An integrated thermal and kinematic model of the temperature, stress, rock type, and displacement fields during early stages of the emplacement ofthe Oman ophiolite was develope...

Large Earthquakes in the Macquarie Ridge Complex: Transitional Tectonics and Subduction Initiation

-While most aspects of subduction have been extensively studied, the process of subduction initiation lacks an observational foundation. The Macquarie Ridge complex (MRC) forms the Pacific-Australia plate boundary between New Zealand to the north and the Pacific-Australia-Antarctica triple junction to the south. The MRC consists of alternating troughs and rises and is characterized by a transit...

Evaluation of Close-Range Photogrammetric Technique for Deformation Monitoring of Large-Scale Structures: A review

Close-range photogrammetry has been used in many applications in recent decades in various fields such as industry, cultural heritage, medicine and civil engineering. As an important tool for displacement measurement and deformation monitoring, close-range photogrammetry has generally been employed in industrial plants, quality control and accidents. Although close-range photogrammetric applica...
