N120/f501 - Tongariro (Matemateaonga Formation) (Pliocene of New Zealand)

Also known as GS 1538

Where: New Zealand (39.4° S, 175.7° E: paleocoordinates 41.5° S, 176.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Early/Lower Pliocene (5.3 - 3.6 Ma)

• Beds containing plentiful fossils. Youngest Tertiary marine sediments in the district. Listed as "Wanganui Series" in the Gregg (1960), but these rocks are now mapped as Matemateaonga Formation, and will be Opoitian (Early Pliocene) in age (Hendy, 2003).

• bed-level stratigraphic resolution

Environment/lithology: coastal; shelly/skeletal, sandy mixed carbonate-siliciclastic sediments

• Shallow, brackish-water assemblage.
• Likely to be shellbed facies.

Size class: macrofossils

Collection methods: quarrying,

• Collected by Gregg et al. Likely to be reposited in IGNS (N.Z. Geol. Surv.) collections.
