S2/f629 - Battery Mbr, Sandhills Creek (Ordovician of New Zealand)

Also known as V 2059; GS 10586

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 upper part of the member and is 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: R.A Cooper. REPOSITORY: New Zealand Geological Survey (now GNS Science), Lower Hutt, New Zealand
