Pleistocene Pb isotope records of crust Haxby from PS75/247-2@en

Lead (Pb) isotope measurements are performed in the ferromanganese crust PS75/247-2, dredged on the southern flank of Haxby Seamount in the Pacific sector of the SO. We apply laser ablation coupled with multiple-collector inductively coupled plasma mass spectrometry (LA-MC-ICPMS) and two-dimensional (2D) mapping techniques. This combined novel approach enables us to confidently resolve orbital Pb isotope variations for the past 800 ka. […]
