T26/f7066 [Mangapokia Fm] (Cretaceous of New Zealand)

Also known as N159/f1066; GS11555

Where: New Zealand (40.9° S, 176.0° E: paleocoordinates 74.9° S, 164.5° E)

• coordinate based on unpublished field data

• outcrop-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: From bed of unknown position within formation.

• bed-level stratigraphic resolution

Environment/lithology: basinal (); lithified, sandy claystone

• ENVIRONMENT: Accumulated by deep-water turbidity currents, hence basinal marine siliciclastic paleoenvironment.
• SPECIFIC LITHOLOGY: Very fine sandy claystone. LITHIFICATION: Lithified, based on facies description.

Size class: macrofossils

Preservation: cast, mold/impression, concretion
