S127/f581 - Otekaike Limestone, Tokarahi Cliff (Oligocene of New Zealand)

Also known as GS5661; Coll# 3071 (Hendy PhD)

Where: New Zealand (45.0° S, 170.6° E: paleocoordinates 51.2° S, 174.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Otekaike Limestone Formation (Otiake Group), Late/Upper Oligocene (28.4 - 23.0 Ma)

• STRATIGRAPHIC RELATIONS: From Otekaike Limestone, which is the upper unit of the Otiake Group, overlying the Kokoamu Greensand, and is overlain by the Gee Greensand of the Kaierero Group. AGE: Duntroonian-Waitakian in text of Gage (1957), but largely Waitakian in Table 3; Waitakian = Late Chattian-early Aquitanian; hereby assigned a Late Oligocene age in ensure collection is not orphaned. STRATIGRAPHIC POSITION: From glauconitic band.

• bed-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, glauconitic, calcareous limestone

• Shallow marine, carbonate. shallow mid shelf to inner shelf
• SPECIFIC LITHOLOGY: Limestone, highly calcareous. LITHIFICATION: Lithified, largely assumed, as no indication is given text of lithification state, although text says unit is cliff forming and highly calcareous, and limestone.

Size class: macrofossils

Reposited in the IGNS

Collection methods: quarrying,

• COLLECTOR: Unknown collectors. REPOSITORY: New Zealand Geological Survey (now GNS Science, Lower Hutt, New Zealand).
