Nisai Group (upper) (Oligocene of Pakistan)

Where: Pakistan (30.8° N, 68.1° E: paleocoordinates 21.1° N, 67.4° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Nisai Group, Early/Lower Oligocene (33.9 - 28.4 Ma)

• STRATIGRAPHIC RELATIONS: From the Nisai Group, which unconformably overlies the Parh Group and Hindubagh intrusions and is conformably overlain by the Murgha Faqirzai shale and Multana Fm. THICKNESS: Ranges from 400-2000 ft. AGE: Oligocene, in text, but refined to Early Oligocene by enter on the basis of stratigraphic contact with Eocene beds of the same formation. STRATIGRAPHIC POSITION: A composite list for the upper part of this group.

• group-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified reef rocks

• ENVIRONMENT: Shallow marine carbonate environment.
• SPECIFIC LITHOLOGY: Reefoidal limestone. LITHIFICATION: Lithified, on the basis on facies description and age.

Size class: macrofossils
