CH/f471 - Red Bluff Tuff, Chatham Islands (Eocene of New Zealand)

Also known as GS 12178; Coll# 2760 (Hendy PhD)

Where: Chatham Islands, New Zealand (44.3° S, 176.3° E: paleocoordinates 54.4° S, 156.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Red Bluff Tuff Formation (Kekerione Group), Waipawan (55.8 - 53.0 Ma)

• AGE: The Red Bluff Tuff is assigned an Late Teurian to early Waipawan local stage=Thanetian-Ypresian age based on biostratigraphy from combination of faunal groups. Most collections come from Waipawan portions of the unit, and therefore the collection is assigned a Ypresian age.

• bed-level stratigraphic resolution

Environment/lithology: offshore; coarse-grained, pebbly, tuffaceous sandstone

• Offshore shelf, siliciclastic environment
• Coarse pebbly tuffaceous sandstone

Size class: macrofossils

Collection methods: quarrying,

• Collections reposited in Institute of Geological and Nuclear Sciences (New Zealand Geological Survey) collections. Collected by MAC (1977)
