Geography
Country:Colombia
Coordinates: 11.1° North, 72.7° West (view map)
Paleocoordinates:9.2° North, 51.9° West (Wright 2013)
Basis of coordinate:based on nearby landmark
Geographic resolution:outcrop
Time
Period: Paleogene Epoch: Paleocene
Stage: Selandian 10 m.y. bin: Cenozoic 1
Key time interval: Selandian
Age range of interval: 61.66 - 59.24 m.y. ago
Stratigraphy
Formation:Manantial
Stratigraphic resolution:bed
Stratigraphy comments: From a bed 2 cm-thick, near the top of informal "Formation II" of Haught, Colley, and Belding (Tropical Oil Company), which is the Manantial Formation according to Etayo-Serna. Belongs to palynological zone T-02 to T-03a (Ayala et al. 2012), which are correlated with the middle Paleocene according to Jaramillo et al. (2011) on the basis of carbon isotopes.
Lithology and environment
Primary lithology:fine,shelly/skeletal calcareous sandstone
Lithology description: Calcareous quartzitic fine-grained sandstone to packed biomicrite
Environment:paralic indet.
Geology comments: According to Etayo-Serna, "Probably lived at a depth between the low tide mark down to thirty meters and was concentrated in a channel or inlet." According to Jaramillo et al. (2007): Upper Manantial Formation contains lenticular, wavy and ripple lamination, and moderate bioturbation at some levels. Cross beds are identified in sandstones near the top. These deposits accumulated in a mixed shallow platform to fine-grained subtidal environments (lagoons), crossed by subtidal channels at the top. Interpreted as a mixed carbonate-siliciclastic marginal to shallow-marine platform by Bayona et al. (2011).
