Análisis estructural de la zona norte del bloque de San Julián, Zacatecas México por Guerra Roel, Rafael

“…Por otro lado, están los cinturones orogénicos cordilleranos los cuales se desarrollan en lugares donde se tiene un ambiente de subducción activo en los márgenes de placas convergentes en donde por lo general el metamorfismo, el engrosamiento de la corteza continental y un cinturón de pliegues y cabalgaduras (CPC) localizado en la parte más alejada de la trinchera son las principales características presentes. Los CPC se localizan en muchas partes del mundo, prácticamente suceden en donde alguna capa de la corteza superior, sufre acortamiento horizontal significativo, generando pliegues y fallas relacionados con cabalgaduras sin sobrepasar las condiciones de metamorfismo de bajo grado. …”
