Late Cenozoic Foraminifera from diamictites of Cape Lamb, Vega Island, Antarctic Peninsula
Foraminiferal assemblages recovered from Cape Lamb sediments on Vega Island are examined and illustrated herein. The foraminifera were discovered in Cenozoic debris and palagonitic breccia lithofacies that crop out at the southwestern tip of Cape Lamb. Among all the Cenozoic diamictite deposits reco...

Foraminiferal assemblages recovered from Cape Lamb sediments on Vega Island are examined and illustrated herein.
