[EN] During the most active rifting stages in the northwestern sector of the Iberian Basin
(Cameros Basin and Aragonese Branch of the Iberian Range), thick sequences of
continental clastic deposits were generated. Sandstone records from Rift cycle 1 (Permo-
Triassic) and Rift cycle 2 (Late Jurassic-Early Cretaceous) show similarities in composition.
Based on the most recent data, this paper describes sandstone petrofacies developed
during both rifting periods. Six petrofacies can be distinguished: two associated with Rift …
