GS 2997 and GS 3894 - Kauru Fm, Five Forks bridge (Paleocene to of New Zealand)

Also known as S136/f574; Coll# 3003 (Hendy PhD)

Where: New Zealand (45.1° S, 170.8° E: paleocoordinates 56.8° S, 162.1° W)

• outcrop-level geographic resolution

When: Five Forks Glauconitic Sandstone Member (Kauru Formation), Selandian to Selandian (61.6 - 56.0 Ma)

• STRATIGRAPHIC RELATIONS: From Five Forks Glauconitic Sandstone of the Kauru Fm, either locally overlying Kakanui Metamorphic Group (Paleozoic) or Papakaio Fm (Piripauan), and overlain locally by Tapui Glauconitic Sandstone (Bortonian). AGE: upper part of Wangaloan of Gage (1957) (disused according to Cooper et al. 2004) = ?late Teurian (current NZ stage usage) = Selandian-Thanetian.

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, glauconitic sandstone

• ENVIRONMENT: Deposited with gentle currents within depths out of reach of strong wave action.
• SPECIFIC LITHOLOGY: Glauconitic sandstone. LITHIFICATION: Presumably lithified, based on age and locally concretionary facies.

Size class: macrofossils

Reposited in the IGNS

Collection methods: quarrying,

• COLLECTOR: Collected by various authors, which may include: Marwick (1924-1944), Laws (1930-1941), and Powell (1942). REPOSITORY: New Zealand Geological Survey (now GNS Science, Lower Hutt, New Zealand).
