Stratigraphy
Formation:Culebra Member:lower
Stratigraphic resolution:bed
Stratigraphy comments: LITHOSTRATIGRAPHY: From the Culebra Formation, which unconformably overlies the Las Cascadas agglomerate; reassigned to La Boca Fm in subsequent publications of Woodring (e.g., 1973, 1982), but further emended by Kirby et al. (2009) to the lower member of the Culebra Formation. AGE: Early Miocene in text; direct date extrapolated from Kirby et al. (1999), =Aquitanian.
Lithology and environment
Primary lithology:planar lamination,fine poorly lithified "shale"
Secondary lithology: carbonaceous mudstone

Includes fossils?Y
Lithology description: Collection assumed to be from lower part of formation. The lower part of the formation comprises: dark-colored, thin-bedded or laminated, fine-grained rocks; carbonaceous or lignitic shale, carbonaceous silty mudstone, tuffaceous siltstone. The upper part comprises: calcareous and sandy strata, and ranges from tuffaceous amd pebbly calcareous sandstone to sandy limestone.
Environment:marine indet.
Geology comments: No paleoenvironmental data reported.
