A 12,800-year-old layer with cometary dust, microspherules, and platinum anomaly recorded in multiple cores from Baffin Bay

Caption

Examples of Fe-rich and silica-rich impact microspherules (a and b) and metallic dust particles (MDPs; c and d) interpreted as cometary dust from Baffin Bay cores. Yellow arrows show particles of FeSi, FeS, and FeCr on microspherules (a and b) and NiFe, low-O2 Fe, and native Fe on metallic particles (c and d). Note folded edges of MDP in panel d.
