S136/f571 - Everett's Quarry [Deborah Volcanic Fm] (Oligocene of New Zealand)

Also known as GS3881

Where: New Zealand (45.2° S, 170.9° E: paleocoordinates 52.0° S, 172.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Deborah Volcanic Formation (Alma Group), Early/Lower Oligocene (33.9 - 28.4 Ma)

• STRATIGRAPHIC RELATIONS: From the Deborah Volcanic Fm, which is the middle unit of the Alma Group, overlain by McDonald Limestone, and overling the Totara Limestone. AGE: Whaingaroan in text of Gage (1957); Whaingaroan = Rupelian to earliest Chattian; here assigned to Early Oligocene to avoid orphaning. STRATIGRAPHIC POSITION: Tuff's below limestone.

Environment/lithology: coastal; lithified, volcaniclastic, conglomeratic tuff

• ENVIRONMENT: Submarine eruptive phase in shallow marine water.
• GENERAL LITHOLOGY: Variable lithology; commonly red-weathering, massive or coarsely current-bedded tuff, scoria, and basaltic breccia. LITHIFICATION: Lithified, assumed on the basis of age, and facies description.

Reposited in the IGNS

• COLLECTOR: Unknown collector. REPOSITORY: New Zealand Geological Survey (now GNS Science, Lower Hutt, New Zealand).
