AMS radiocarbon dating on Campos Basin, Southeast Brazilian Continental Slope

We present results on radiocarbon dating of foraminifera shell samples, collected on the upper slope of Campos Basin, in Southern Brazil. This is the first time that the sedimentation rate of this area is measured with a fine scale (cm) stratigraphy. 14C ages vary from (2560±80) years. BP at the top...

Summary:We present results on radiocarbon dating of foraminifera shell samples, collected on the upper slope of Campos Basin, in Southern Brazil. This is the first time that the sedimentation rate of this area is measured with a fine scale (cm) stratigraphy. 14C ages vary from (2560±80) years. BP at the top to (7260±80) years. BP at the bottom of the sediment column. The mean accumulation ratio for the whole column is (6.2±0.7) cm/kyears.
