α and β show details of the magnetic signature of two greigite-bearing samples: α from the Younger Dryas and β from the ACR. The First Order Reversal Curve (FORC) diagram is dominated by oval central peak at 60 mT indicating the presence of greigite with the addition of a thin central ridge indicative of biogenic particles (magnetofossils).
