Abstract
La cuenca del Duero es una de las depresiones intramontañosas alpinas
más alta de Europa (>800 m). Considerada como una cuenca de antepaís
del orógeno cantabro-pirenaico, su génesis no puede explicarse únicamente
por el acortamiento cortical alpino, siendo necesario el análisis conjunto de
la deformación a escala litosférica. En este trabajo presentamos los resultados
de una serie de modelos analógicos que permiten analizar la contribución
de la litosfera y los procesos de reajuste isostático en las variaciones observadas
en la profundidad del Moho bajo la cuenca y las cadenas montañosas
adyacentes, así como explicar su elevada altura topográfica
The Duero Basin is one of the highest alpine intra-mountain depressions in Europe (>800 m). Often considered as part of the Cantabrian-Pyrenean foreland basin, its origin cannot be supported only by the alpine crustal shortening; therefore the combined analysis of lithospheric-scale deformation is required. In this study we present the results of a series of analogue models that allowed us to gain insights into the contribution of the lithospheric deformation and subsequent isostatic processes, which may explain the observed variations in the depth to the Moho underneath the basins and nearby mountain ranges, as well as the high topography of the basin
