Influencia de un bloque rígido en un sistema de fallas de rumbo: modelamiento análogo

this work addresses the kinematic effects of a rigid block in strike-slip systems by using analogue models. the experiments (size, behaviour of materials) were scaled down in order to represent deformation of the tested rheologic contrast conditions in deformation. two main parameters were tested: the configuration of the rigid block, changing its form and size, and the amount of displacement. the experiments evidenced the development of rotations, faults and folds along the fault trajectory, as resulting from the presence of the rigid block during the deformation. testing of diverse geometric situations may be used for comparison to strike-slip fault systems in which different lithologies and rheologic behaviour exist, for example, presence of the 'limón verde rigid core' along the domeyko fault system, just south of chuquicamata.
