USGS 25731, Kere River, Santo Island (Pleistocene of Vanuatu)

Where: Vanuatu (15.6° S, 167.0° E: paleocoordinates 15.6° S, 166.9° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Middle Pleistocene (0.8 - 0.1 Ma)

• Coarse shelly clays and coarse shelly sands from in situ between bedding planes (0.61 m) laterally for 2.4 m, between 0.3 and 0.9 m above water level about 206 m up stream from S end of exposures. Very well-preserved ahermatypic corals (Flabellum spp.) collected in 2006 from Kere 2 have been dated by the Uranium/Thorium method and established an age of 232 +/- 10 ka. The same species of coral from the overlying deposit of Kere 1 gave an age of 133 +/- 5.5 ka. These reliable benchmarks suggest that the Kere sequence was deposited during the warmer Marine Isotope Stages (also named OIS for "Oxygen Isotope Stage") MIS 7 (Kere 2) and MIS 5 (Kere 1). (Lozouet et al., 2011). These historical collections are apparently from the classic Kere Shellbed (Kere 1). From the upper 1.22 m of a 1.37 m section.

• group of beds-level stratigraphic resolution

Environment/lithology: unlithified, shelly/skeletal, calcareous sandstone

• It is an unconsolidated (or poorly consolidated) calcareous silty gravel consisting of 50/70% shell fragments. Dissolution and recrystallisation have cemented parts of the deposit (Lozouet et al., 2011).

Size class: macrofossils

Collected by T.R. Waller, J. Bolango, W.C. Blow; reposited in the USNM
