Late Quaternary benthonic foraminifera in a bathyal core from the Leeward Islands, Lesser Antilles, NE Caribbean Sea

摘要

The 3.13 m long bathyal piston core En20-2 from the northern Leeward Islands (17°49 9'N, 6.3°02,4'W, water depth 680m) was sampled every 20cm, The Pleistocene-Holocene boundary occurred at 107 cm, and the base of the core lay above the Atlantic extinction of Pulleniatina obliquiloculata (34 ka BP), The core yielded throughout both (a) a deep-water association (DWA) of middle bathyal benthonic foraminifera and (b) a shallow-water association (SWA; up to 56% of total recovery) comprising back-reef, epiphytal species The environmental trends suggested by the two groups are compared.
