Stratigraphy
Formation:Gatuncillo
Stratigraphic resolution:bed
Stratigraphy comments: Limestone In Madden basin, the Gatuncillo Formation is overlain by Caimato Formation and overlies Cretaceous basement. The thickness of the foramtion is difficult to estimate, but not more than 300 m. Limestones are extensive. Algal or algal-foraminiferal limestones dominate the upper part of the formation. Other facies include echinoid bearing limestones, soft and coralliferous limestones. Siliciclastic facies dominate the formartion and include fine-grained and sandy strata.
Lithology and environment
Primary lithology:shelly/skeletal lithified "limestone"
Includes fossils?Y
Lithology description: Limestone. Algal or algal-foraminiferal limestones dominate the upper part of the formation. Other facies include echinoid bearing limestones, soft and coralliferous limestones.
Environment:carbonate indet.
Geology comments: Carbonate facies, including algal and coral-rich limestones. No further paleoenvironmental data.
