Reply to van Hoesel et al.: Impact-related Younger Dryas boundary nanodiamonds from The Netherlands

Van Hoesel et al. claim that the nano-diamond-rich layer atAalsterhut postdates the YDB by 200 y. However, that claim is indefensible. The calibrated radiocarbon ranges from Aalsterhut and Murray Springs are virtually indistinguishable. All dates for the nanodiamond-rich layers found at those two ke...

Description
Summary:Van Hoesel et al. claim that the nano-diamond-rich layer atAalsterhut postdates the YDB by 200 y. However, that claim is indefensible. The calibrated radiocarbon ranges from Aalsterhut and Murray Springs are virtually indistinguishable. All dates for the nanodiamond-rich layers found at those two key sites are consistent with the age of the cataclysmic YDB impact event, now clearly defined at the beginning of the Younger Dryas cooling episode in the Greenland ice sheet.
