Geography
Country:Ecuador State/province:Manabi
Coordinates: 1.0° North, 79.6° West (view map)
Paleocoordinates:0.7° North, 78.8° West
Basis of coordinate:based on political unit
Geographic resolution:outcrop
Time
Period:Neogene Epoch:Pliocene
Stage:Zanclean 10 m.y. bin:Cenozoic 6
Key time interval:Early/Lower Pliocene
Age range of interval:5.33300 - 3.60000 m.y. ago
Stratigraphy
Formation:Esmeraldas
Stratigraphic resolution:formation
Stratigraphy comments: AGE: Stated to be Late Miocene in text; Early Pliocene following Beu (2010). COMMENTS: thought to be equivalent to the Borbon formation of the Rio Santiago section, resting unconformably on top of conglomerate beds containing Turritella altilira and other Miocene fossils probably not greater than 300 meters in thickness overlain unconformably by massive to wellbedded brown sandstones

The beds at Quebrada Camarones have a low notherly to nearly horizontal dip, the cutbanks showing bare exposures sometimes rising as high as 30 feet
Lithology and environment
Primary lithology:fine,brown,yellow lithified sandstone
Secondary lithology: lithified sandstone
Includes fossils?Y
Lithology description: thin bedded to massive tuffaceous mudstones sometimes with interbeds of soft sandstones. small or medium-sized rounded pebbles are scattered throughout the formation, or more rarely concentrated into minor beds or seams of conglomerate. Large calcareous concretions, some rounded or with an irregular rootlike shape, generally with hollow centers are common at many places. The beds are highly foraminiferal, with pelagic types, often pure enough to form a foraminiferal oozelike sediment. On the fresh surface of the rock platform, the formation is hard, and of a gray-black or dark olive-green color.
Environment:marine indet.
Geology comments: deep water fauna with a few shallow water forms that were badly worn, indicating transportation, while deep-water fauna were in perfect condition, suggesting turbidity currents.
