Stresses in an overthrust sheet and propagation of thrusting: an airy stressfunction solution

Article Abstract:

Given rear and front horizontal forces acting on an elastic wedge-shaped overthrust sheet, an Airy stress solution can be used to obtain the state of stress on the sheet's lower boundary. Position along the lower boundary determines the normal and shear stresses for nonlinear components of the forces exerted on the block's vertical edges, and for nonzero upper and lower boundary slopes. Since position determines the frictional function, only on a part of the thrust is strength exceeded, thus undermining the assumption that the whole thrust sheet is simultaneously displaced on the basal plane.

Tectonics of the Punta Bianca promontory: insights for the evolution of the Northern Apennines-Northern Tyrrhenian sea basin

Article Abstract:

The structural study of the La Spezia Gulf (Punta Binaca promontory) combined with the available geological and geophysical data enables a detailed reconstruction of the complicated post collisional evolutionary path for the 'Tyrrehenian side' of the Northern Apennines. The late orogenic extension is supposed to be overprinted by strike-slip tectonics.

Synchronous and velocity-partitioned thrusting and thrust polarity reversal in experimentally produced, doubly-vergent thrust wedges: implications for natural orogens

Article Abstract:

A non-steady state, two-stage evolutionary path for doubly-vergent orogenic thrust wedges developed in response to orthogonal convergence is presented. Analysis of the time distribution of the dominant vergence may offer a further tool to constrain the subduction direction in natural orogens.
