Eastern Wairarapa [Mangapokia Fm] (Cretaceous of New Zealand)

Where: New Zealand (41.2° S, 175.7° E: paleocoordinates 75.1° S, 163.3° E)

• coordinate based on nearby landmark

• basin-level geographic resolution

When: Mangapokia Formation (Pahaoa Group), Motuan (103.3 - 99.5 Ma)

• STRATIGRAPHIC RELATIONS: From the Mangapokia Fm, which is unconformably overlain by the Gentle Annie and Springill Fm (Albian) of the Mangapururpuru Gp. The Taipo and Stronvar Mbrs interfinger with the Mangapokia Fm. AGE: Motuan (=Albian), on the basis of macrofossil biostratigraphy. STRATIGRAPHIC POSITION: Composite for entire formation.

• formation-level stratigraphic resolution

Environment/lithology: basinal (); lithified sandstone and lithified siltstone

• ENVIRONMENT: Accumulated by deep-water turbidity currents, hence basinal marine siliciclastic paleoenvironment.
• SPECIFIC LITHOLOGY: Complexly deformed, thin- to thick-bedded, moderately indurated flysch-like alternating sandstone and siltstone, minor siltstone, and scattered spilitic igneous rocks with associated volcanogenic sediments and chert. LITHIFICATION: Lithified, based on facies description.

Size class: macrofossils

Preservation: cast, mold/impression

Reposited in the IGNS

Collection methods: surface (in situ),

• COLLECTOR: Multiple collectors. REPOSITORY: GSNZ (now GNS Science, Lower Hutt, New Zealand).
