N112/f512 - Tongariro (Landon Series) (Oligocene of New Zealand)

Also known as GS 6082

Where: New Zealand (39.0° S, 175.5° E: paleocoordinates 49.1° S, 179.1° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Oligocene (33.9 - 23.0 Ma)

• Of the Landon series, no formal lithostratigraphic determination. Waitakian age (late Oligocene). The Landon series unconformably overlies Mesozoic greywacke and argillite, and is overlain, unconformably by greywacke conglomerates of the Taranaki series. In Okupata Stream is exposed 150 ft of hard limestone, overlain by 150 ft of calcareous greensand with some bands of mudstone.

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, brown, yellow limestone

• Shallow-water siliciclastic environment.
• Softer limestone; hard, brownish-cream limestone.

Size class: macrofossils

Collection methods: Collected by Gregg et al. (N.Z. Geo. Surv.) Collections probably reposited in IGNS (USGS) collections.
