Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Castilletes Formation, which conformably overlies the Jimol Formation (early Miocene) and is unconformably overlain by the Ware Formation. AGE: Burdigalian-Langhian, on the basis of macrofaunal composition and stratigraphic position; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: Likely in lower part of the Castilletes Fm, but in a faulted part of the sequence; from 49 m above Jimol/Castilletes contact. |
Lithology and environment

Includes fossils? | Y |
Lithology description: SPECIFIC LITHOLOGY: Unconsolidated shell bed, silty matrix. LITHIFICATION: Unlithified, as determined in the field and based on museum-reposited specimens. | |
Environment: | lagoonal |
Geology comments: ENVIRONMENT: Shallow marine (0-5 m), siliciclastic, probably reduced salinity. |
