S2/f546 - Battery Mbr, Slaty Creek (Ordovician of New Zealand)

Also known as GS 9950; V 1048

Where: New Zealand (40.7° S, 172.4° E: paleocoordinates 13.1° N, 167.7° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Battery Member (Aorangi Mine Formation), Yapeenian (470.3 - 467.3 Ma)

• STRATIGRAPHIC RELATIONS: Derived from Battery Member of Aorangi Mine Fm, which overlies the Anthill Black Shale Mbr (Lancefieldian-Castlemanian). THICKNESS: 150 m in type section. AGE: Battery Mbr is upper Castlemainian and lower Yapeenian, but collection is derived from the zone of Oncograptus, corresponding to the uppermost part of the member and is lower Yapeenian. STRATIGRAPHIC POSITION: Presumably uppermost part of Battery Mbr.

• bed-level stratigraphic resolution

Environment/lithology: deep-water; poorly lithified, gray, blue, sandy siltstone

• ENVIRONMENT: No environmental data reported. Presumably shallower (coarser, more oxygenated facies) than underlying Anthill Black Shale Mbr, and silicicastic, hence assigned to a "deep-water indet." environment.
• SPECIFIC LITHOLOGY: Medium to dark, soft, blue-grey massive siltstone with interbedded bands of hard gery quartz sandstone and black slate. LITHIFICATION: Poorly lithified, as text states lithology to be soft, and contrasts this with interbeds that are "hard" and "slate".

Size class: macrofossils

Preservation: original carbon

Reposited in the IGNS

Collection methods: bulk,

• COLLECTOR: G. Smith (see Smith 1966, p. 174); re-collected by R.A. Cooper (1967). REPOSITORY: New Zealand Geological Survey (now GNS Science), Lower Hutt, New Zealand

Taxonomic list

• COMPLETENESS: Only graptolite taxa listed, however no other faunas mentioned in text, except rare phyllocarid crustaceans. IDENTIFICATIONS: Older collections re-examined by R.A. Cooper, otherwise lists collected and identified by R.A. Cooper. COMMENTS: Re-investigation of Smiths collection by R.A. Cooper revealed two distinct assemblages/facies, only one of which "assemblage 1" was recovered during re-collection.
