THE CRISIS WE ARE LIVING IS THE RESULT OF A PROCESS OF EXPLOITATION imposed by financial capitalism in the last decades. In this article, we focus on the concrete dimension [...]

We present the application of the HCA (hybrid cellular automata) numerical modeling technique to the evolution of compressional fault-bend anticlines involving layers that have competency contrasts and a mechanical stratigraphy. The new modeling results show that, for competent hanging-wall layers, (1) the fault style is not preserved in the overlying fold; (2) fold development is not self-similar, and rotational growth wedges develop in the fore-limb when syntectonic sedimentation occurs; and (3) balanced fault-bend anticlines can develop for ramp cutoff angles as high as 60 [degrees]. These results compare favorably with field examples and laboratory analogues and dramatically broaden the applicability of fault-bend folding to model the evolution of thrust-related anticlines. Keywords: folding, faulting, kinematics, syntectonic processes, numerical models.

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.
