Numerical investigation of parameters influencing back-thrust development in outer wedge fronts of fold-and-thrust belt systems [PDF]

Solid Earth
Thrusting in fold-and-thrust belts can manifest in different styles. Here we investigate the parameters influencing back-thrust development over fore-thrust development at the frontal part of fold-and-thrust belts using numerical geomechanical forward ...
