The Repetto Formation is a Pliocene epoch sedimentary unit in the greater Los Angeles Basin composed primarily of sandstone and conglomerate.
The unit records deposition of a submarine fan environment at lower bathyal depths, and is recognized as a productive petroleum reservoir.
[4] Other researchers maintain that the Repetto and Pico Formations are distinct stratigraphic units, and that the use of the name "Fernando Formation" should be stopped due to several issues with stratigraphic correlation and access to the type section.
