AB Sequence stratigraphy principles are compared to similar geometrica architectures in lacustrinesediments of Miocene age in the Duero Basin (NW Spain). The studied sequence shows anerosive base wirh multiple scours, a lower reach that shows an aggradational pattern, firstdeepening and later and mostly shallowing upward, foffowed by an upper reach composed byprograding c1inoforms deeper than the immediately underlying deposits. The upper boundary oflhe sequence is another erosive surface with multiple scours. This sequence can be compared toa type 2 sequence al Van Wagoner et al. (1988). Despite the similarities concerning geometriesand their evolution, there are some differences about water depth evolution and thus about faciesevolution thaat show reverse relations in the sequence stratigraphy model and our lacustrine case.Similarities are due lO common evolulion of base level in both cases. Differences arise from thedifferent amount of influence of sedimentation and subsidence in marine and lacustrine systems.
