Naseby GS 1904 (Oligocene of New Zealand)

Also known as GSNZ coll. 1904; possibly same locality as GSNZ coll. 494

Where: Central Otago, New Zealand (45.0° S, 170.1° E: paleocoordinates 51.2° S, 175.5° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Naseby Greensand Formation (Stranraer Group), Late/Upper Oligocene (28.4 - 23.0 Ma)

• Described in text as from units of the Naseby Series (now Naseby Greensand), part of the Pareora Formation of Hutton (1875). From Bishop (1979): Naseby Greensand (Stranraer Group) is approximatey 250-300 m thick, underlain by metamorphosed schist or siltstone of the Eocene Swinburn Formation (Stranraer Group), and overlain conformably by current-bedded quartz sands and gravels of the late Oligocene/early Miocene Wedderburn Formation (Stranraer Group).

•Bishop, D.G. 1979: Sheet 135, Ranfurly (1st ed.) "Geological Map of New Zealand 1:63 360". N.Z. Dept. Sci. Ind. Res., Wellington

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, coarse-grained, green sandstone

• From Bishop (1979) "....part of marine-terrestrial transgressive-regressive sequence of the Stranraer Group in the Maniototo basin"; "marine wedge thins rapidly westward,"
• Listed as "greensand". From Bishop (1975): The greensand is a coarse and quartzose, with common bands, nodules and patches of limnoite,, and with thin lensoid beds of angular quartz pebbles.....Macrofossils are numerous.

Size class: macrofossils
