S136/f497 - Rifle Butts Fm, Rifle Butts (Miocene of New Zealand)

Also known as GS958, GS2218; Coll# 3084 (Hendy PhD)

Where: New Zealand (45.1° S, 170.9° E)

• Paleocoordinates: 46.6° S, 174.5° W (Wright 2013)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Rifle Butts Formation (Kaierero Group), Altonian (19.0 - 15.9 Ma)

• STRATIGRAPHIC RELATIONS: From the Rifle Butts Fm, which gradationally overlies the Gee Greensand of the Kaierero Group, and is overlain by the Kurow Group. AGE: Hutchisonian-Awamoan in text of Gage (1957); late Altonian = Burdigalian-earliest Langhian; hereby assigned to the Altonian. STRATIGRAPHIC POSITION: Lower part of the formation.

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, fine-grained, glauconitic, shelly/skeletal, gray, green sandstone

• ENVIRONMENT: Shallow marine, siliciclastic. Increasingly rapid accumulation of sediment in deepening water.

• SPECIFIC LITHOLOGY: Fine, glauconitic, greenish-grey sandstone containing brachiopods and molluscs grading up to a fine silt or mudstone. Concretionary bands and layers of tabular concretions indicate bedding in otherwise unstratified sediment. Fossils are disseminated through the silt, and also entombed in concretions and concentrated in shell-limestone lenses. LITHIFICATION: Poorly lithified, largely assumed, as no indication is given text of lithification state, except that concretionary layers are contrasted with the background lithology.

Size class: macrofossils

Preservation: concretion

Reposited in the IGNS

Collection methods: quarrying,

• COLLECTOR: Collected by Park (1915-1916) and Marwick (1925). REPOSITORY: New Zealand Geological Survey (now GNS Science, Lower Hutt, New Zealand).

Taxonomic list

• COVERAGE: Exhaustive for bivalvia, gastropoda, and polyplacophora. IDENTIFIER: Identifications compiled from previously published accounts and reassessments of NZGS collections, by various paleontologists. NOMENCLATURE: Somewhat antiquated but identified by specialist and often to subgeneric and species resolution.
