Abstract

A description is offered of a sedimentary body from the Miocene situated in the Ciudad Rodrigo Basin (Spain). The lithosome is interpreted as a coarse-grained meander loop whose development has been conditioned by the paleorelief of the eastern border of the basin. Five sedimentary units are established; these are related to the subenvironments of scour-pool, low point-bar, chute channels, accretionary bank and overbank deposition. The facies comprising the meander loop are articulated in a complex sequence whose most salient characteristic is the absence of a well-defined fining upward trend. The meander loop is composed of two adjointing point-bars exhibiting different sections as the result of a change in the direction of the displacement of the channel.
