Geography
| Country: | Colombia | State/province: | La Guajira |
| Coordinates: | 12.0° North, 71.3° West (view map) | ||
| Paleocoordinates: | 11.4° North, 68.5° West | ||
| Basis of coordinate: | unpublished field data | ||
| Geographic resolution: | small collection |
Time
| Period: | Neogene | Epoch: | Miocene |
| Stage: | Langhian | 10 m.y. bin: | Cenozoic 5 |
| Key time interval: | Langhian | ||
| Age range of interval: | 15.98000 - 13.82000 m.y. ago |
Stratigraphy
| Formation: | Castilletes | Member: | middle Castilletes | ||
| Regional section: | Cocinetas | Regional bed: | 168 m | ||
| Regional order: | bottom to top | ||||
| Stratigraphic resolution: | bed | ||||
| 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: Langhian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: Probably from middle member of Castilletes Fm; immediately underlying Ware Fm; from an estimated 168 m above Jimol/Castilletes contact. | |||||
Lithology and environment
| Primary lithology: | unlithified siltstone |
| Lithology description: SPECIFIC LITHOLOGY: Unconsolidated silty matrix. LITHIFICATION: Unlithified, as determined in the field and based on museum-reposited specimens. | |
| Environment: | lagoonal |
| Geology comments: ENVIRONMENT: Very shallow marine, probably slightly reduced salinity. | |
