Stratigraphy
Formation:Punta Pelada
Stratigraphic resolution:formation
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Punta Pelada Fm, which unconformably overlies and is laterally equivalent to the Senosri Fm (Late Eocene-Early Miocene) and is unconformably overlain by the Uscari Fm (Early-Late Miocene). THICKNESS: From beds with section of no more than 25 m. AGE: Late Oligocene to Early Miocene. Placed in the Late Oligocene by enterer. STRATIGRAPHIC POSITION: From beds throughout section.
Lithology and environment
Primary lithology: lithified sandstone
Secondary lithology: lithified "limestone"
Includes fossils?Y
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Sandstones, conglomerates and limestone. LITHIFICATION: Lithified, based on figured specimens.
Environment:deep subtidal shelf
Geology comments: ENVIRONMENT: Shallow marine environment (50-80 m depth), influenced by currents and localized clastic input.
