[ES] Este trabajo aporta nuevos datos cartográficos y sedimentológicos para aclarar la controvertida evolución tectónica extensional de la Cuenca de Cameros (N de España). La geometría actual del borde norte de la cuenca representa la continuación de lineaciones tardivariscas NO-SE y SO-NE reconocidas en la Cuenca Vasco-Cantábrica, a lo largo de las cuales se produjo una importante tectónica salina sin-extensional. En la zona de estudio, la distribución irregular de los depósitos plásticos del Keuper es interpretada aquí como debida a una movilización sin-extensional. De este modo, la estructuración tardivarisca del basamento y las movilizaciones de Keuper, asociadas a ella, permiten explicar la arquitectura y distribución de las unidades sin-extensionales del relleno de la cuenca.
[EN] This work provides new mapping and sedimentological data to shed light on the controversial extensionaltectonic evolution of the Cameros Basin (N Spain). The present-day geometry of the northern margin of the basin represents the continuation of NW-SE and SW-NE late-variscan lineaments of the Basque-Cantabrian Basin, along which important syn-extensional salt-tectonics occurred. In the study area, the irregular distribution of the Keuper plastic deposits is interpreted here as due to syn-extensional mobilization. Thus, the late-variscan basement structure and the Keuper mobilizations related to it, allow explaining the architecture and distribution of the syn-extensional units of the basin infill.
