J32/f7585 - Stillwater Mudstone, Karoro Brickworks Quarry (Miocene of New Zealand)

Also known as S44/f585; GS 3341

Where: New Zealand (42.5° S, 171.2° E: paleocoordinates 48.7° S, 173.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Stillwater Mudstone Formation (Blue Bottom Group), Waiauan (13.1 - 11.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Stillwater Mudstone, which overlies the Inangahua Formation (Otaian-Altonian) and underlies the Eight Mile Formation (Tongaporutuan-Waipipian) of the Blue Bottom Group. The Stillwater Mudstone includes the Tindale Limestone Member. AGE: Macrofossil biostratigraphy indicates a Waiauan-Tongaporutuan age, while microfossils suggest a Waiauan age.

• bed-level stratigraphic resolution

Environment/lithology: deep-water; unlithified, concretionary, gray, blue siltstone

• ENVIRONMENT: Upper, but not uppermost, bathyal environment, probably in the range of 400-800 m.
• SPECIFIC LITHOLOGY: Massive or indistinctly bedded blue-grey siltstone with very little sand-sized material and with scattered, irregularly tabular concretions. LITHIFICATION: Unlithified based on figured specimens.

Size class: macrofossils

Preservation: original aragonite, original calcite

Collection methods: quarrying,

• COLLECTOR: A.G. Beu, M. Gage, R.H. Hoskins, S.M. Jarman, P.A. Maxwell, S.G. Nathan. REPOSITORY: Mostly reposited at New Zealand Geological Survey (now GNS Science), Lower Hutt, New Zealand
