Resumen
Las zonas transversales son estructuras tectónicas paralelas u oblicuas a la dirección de acortamiento. Las rampas laterales son estructuras tectónicas heredadas y son comprendidas en una zona transversal. Durante el acortamiento las zonas transversales son usualmente confundidas con un sistema de fallas de rumbo. En este trabajo se implementaron 36 modelos análogos en condiciones de comportamiento frágil usando dos rampas frontales conectadas a través de una rampa lateral, estas rampas poseen diferentes inclinaciones (30º, 45º y 60º), con el fin de identificar las características de las rampas laterales en cinturones plegados y cabalgados. Los experimentos fueron ejecutados usando una mesa de modelamiento tipo subducción con arena seca y un bloque de madera, los cuales representan una corteza frágil y un bloque rígido, respectivamente. Las fallas y pliegues principales crecen paralelos a las rampas frontales. El cabeceo de estas estructuras se correlaciona a la inclinación de la rampa lateral. Las fallas oblicuas buzan en la dirección opuesta a la inclinación de la rampa lateral, mientras que las fallas normales paralelas a la rampa lateral solo ocurrieron en el modelo de alta inclinación. La inclinación de las rampas laterales controla el cabeceo y la rotación de los pliegues y los cabalgamientos. Independientemente de la inclinación de las rampas laterales, en vista de mapa, las principales características usadas para identificar rampas laterales son i) interrupción de las estructuras a lo largo del rumbo en el área de la rampa lateral, y ii) fallas oblicuas relacionadas a las estructuras de las rampas frontales.
