The Lodo Formation

The Lodo Formation is a Paleocene to Lower Eocene-age geologic unit in the San Joaquin Valley. A widespread unconformity at the base of the Domengine Sandstone Member of the Lodo has removed most of the Paleocene section in Calilfornia so that the Cenozoic section in most parts of the state rests unconformably on Mesozoic or older strata.
