CH/f481 CH/f482 - Chatham Islands [Te One Lmst] (Eocene to of New Zealand)

Also known as GS 12177, GS 12178; Coll# 2767 (Hendy PhD)

Where: New Zealand (43.8° S, 176.5° W: paleocoordinates 52.2° S, 152.5° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Te One Limestone Member (Red Bluff Tuff Formation), Bortonian to Bortonian (42.6 - 36.7 Ma)

• AGE: The Te One Limestone is assigned an Kaiatan-early Whaingaroan local stage=Priabonian-early Rupelian age based on biostratigraphy from combination of faunal groups. The particular collection is dated as Bortonian-Kaiatan=Bartonian-early Priabonian.

• bed-level stratigraphic resolution

Environment/lithology: offshore; poorly lithified, shelly/skeletal, calcareous grainstone

• Molluscan assemblages give little indicatoon of depth of deposition, but an inner-middle shelf setting is suggested; siliciclastic environment
• Soft bryozoan rich calcarenite

Size class: macrofossils

Collection methods: quarrying,

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