[1] Drilling during ODP Leg 209, dredging, and submersible dives have delineated an anomalous stretch of the Mid-Atlantic Ridge north and south of the 15 200N Fracture Zone. The seafloor here consists dominantly of mantle peridotite with gabbroic intrusions that in places is covered by a thin, discontinuous extrusive volcanic layer. Thick lithosphere (10–20 km) in this region inhibits magma fro...

Abstract Fault damage zones have a higher upscaled permeability than the host rock because of fracture intensity therein. Fracture distribution in zone depends highly on geometry fault segments. However, precise images architectural elements large-scale faults at depth are difficult to obtain by seismic acquisition and imaging techniques. We present numerical method that generates segments mult...

A physically based fault conceptual model is presented for modeling multiphase flow and transport processes in fractured rock of fault zones. In particular, we discuss a general mathematical framework model for dealing with fracture-matrix interactions, which is applicable to both continuum and discrete fracture conceptualization in fault zones. In this conceptual model, faults or fault zones o...

[1] The Mid-Atlantic Ridge around the Fifteen-Twenty Fracture Zone is unique in that outcrops of lower crust and mantle rocks are extensive on both flanks of the axial valley walls over an unusually long distance along-axis, indicating a high ratio of tectonic to magmatic extension. On the basis of newly collected multibeam bathymetry, magnetic, and gravity data, we investigate crustal evolutio...

[1] We investigate the development of fracture distributions as a function of displacement to determine whether damage around small and large faults is governed by the same process. Based on our own field work combined with data from the literature, we find that (1) isolated single faults with small displacements have macrofracture densities that decay as r, where r is distance from the fault p...

We use a two-dimensional plane strain dynamic rupture model with strongly rate-weakening friction and off-fault Drucker-Prager plasticity to model damage zones associated with buried second-order thrust faults observed in the SSC reservoir. The modeling of ruptures propagating as self-sustaining pulses is performed in the framework of continuum plasticity where the plasticity formulation includ...

abstract the study of natural disasters is one of the most important primary principles for the growth of developing cities and the development of infrastructures. to this end, evaluating geodynamic activities using morphological data is considered one of the most pivotal applied methods. in this study, it was tried to detect active faults in yazd province using desert studies and remote sensin...

in this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for v47/660kw wind turbine operated in manjil wind farm, gilan province, iran. according to the acquired data from iran wind turbine industry, common faults of the wind turbine such as sensor fault...
