文摘
10Be/9Be ratios and 10Be-fluxes yield equivalent results from glaciomarine sediments.
10Be-systematic variability mainly obeys to glacio-climatic condition changes.
10Be production proxies do not allow to characterize the geomagnetic features in PC16.
Denudation rates are steady except for brief ice surging episodes coeval to H-events.
10Be concentration is controlled by freshwater inputs from regional Ice Sheets.
