A revised Pliocene record for marine-Sr-87/Sr-86 used to date an interglacial event recorded in the Cockburn Island Formation, Antarctic Peninsula
We present a revised Sr-87/Sr-86-curve for marine-Sr in the interval 2.5-4.5 Ma using analysis of Orbulina universa from the Middle Pliocene type section in Sicily (Punta Piccola section) and a mixed assemblage of planktonic foraminifera from ODP Site 758A and B. The new calibration is used, togethe...
