Rosario Group


The Rosario Group is a Late Cretaceous geologic group in southwestern California and northwestern Baja California. In older literature it was named Rosario Formation.
The Rosario Group includes the Point Loma Formation and Cabrillo Formation subunits in San Diego County, California.
The sedimentary structures of the Rosario Group apparently were formed in a nearshore shelf environment, probably a local embayment.
