Station MR-20 [Mba Group] (Pliocene of Fiji)

Where: Fiji (17.6° S, 177.7° E: paleocoordinates 19.1° S, 177.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Mba Group, Late/Upper Pliocene (3.6 - 2.6 Ma)

• STRATIGRAPHIC RELATIONS: Estimated to be from the Mba Group, which overlies the Koroimavua Group (?Early Pliocene), and is overlain by the Verata Group (?Early Pleistocene). AGE: Late Pliocene on the basis of foraminiferal biostratigraphy and stratigraphic position. STRATIGRAPHIC POSITION: From unknown position with lithostratigraphic unit.

• bed-level stratigraphic resolution

Environment/lithology: poorly lithified lithology not reported

• ENVIRONMENT: Shallow marine carbonate facies.
• SPECIFIC LITHOLOGY: Not stated, but presumably carbonate. LITHIFICATION: Poorly-lithified, on the basis of figured specimens.

Size class: macrofossils
