GS 7373 - Aorere Group, Graptolite Hill (Ordovician of New Zealand)

Where: New Zealand (41.1° S, 172.5° E: paleocoordinates 12.1° N, 171.3° W)

• outcrop-level geographic resolution

When: Peel Formation (Golden Bay Group), Gisbornian (458.4 - 452.7 Ma)

• LITHOSTRATIGRAPHY: Upper Aorere Series=group of Henderson et al. (1959). AGE: Lower Gisbornian. Cooper (1971) notes that this is now the Peel Formation, which overlies the Douglas formation (PJW).

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified shale and lithified sandstone

• ENVIRONMENT: Environmental data not reported in text.
• SPECIFIC LITHOLOGY: Interbeded slates, quartzites, and sandstones. LITHIFICATION: Assumed to be lithified as rocky types are slightly metamorphosed (e.g. slates).

Size class: macrofossils

Reposited in the IGNS
