Khari Nadi Fm (Miocene of India)

Where: India (23.4° N, 68.8° E: paleocoordinates 16.8° N, 67.5° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Khari Nadi Formation, Aquitanian (23.0 - 20.4 Ma)

• STRATIGRAPHIC RELATIONS: From Khari Nadi Fm, which unconformably overlies the Maniyara Fort Fm (Oligocene) and is conformably overlain by the Kharinadi Fm (Burdigalian). AGE: Aquitanian (Early Miocene). Biostratigraphic assignment based on larger foraminifera (see Biswas, 1992). STRATIGRAPHIC POSITION: From ocherous limestone horizon, from unknown position within formation.

• formation-level stratigraphic resolution

Environment/lithology: marine; poorly lithified, bentonitic limestone and poorly lithified siltstone

• ENVIRONMENT: Environmental data not reported in text.
• SPECIFIC LITHOLOGY: Ocherous limestone, within formation that is typically variegated siltstones and sandstones.

Size class: macrofossils
