... core complexes. We formally propose the names Magdalena, Cuesta, El Torre?n, and Tubutama Formations for mid-Tertiary sedimentary and volcanic rocks of the upper plates in the Magdalena and Tubutama basins. The name Baucarit Formation should be restricted to the younger sedimentary rocks overlying...
