Boliden boring bp2, 718-720 cm depth (Pleistocene of Sweden)

Where: Sweden (64.8° N, 20.4° E: paleocoordinates 64.8° N, 20.4° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

• Radiocarbon dated at c. 45,000 BP and >40,000 BP, most probably deposited during an Early or Middle Weichselian interstadial, but the initial or final stage of an interglacial (Eemian) is also possible.

Environment/lithology: terrestrial; unlithified siltstone

• Mainly coarse silt and fine sand containing organic material with macroscopic plant remains

Size class: macrofossils

Collected in 1981

Collection methods: core
