QuestionsYounger Dryas impact hypothesisAre the proposed markers (microspherules, nanodiamonds, shocked quartz, meltglass) reproducible and diagnostic of impact?Answer

The markers are background cosmic dust, volcanic or anthropogenic spherules, fire products or misidentified carbon, concentrated by sedimentary processes.
Where it stands
Most likelyIts tests supported it: three pieces of evidence for, none against. It needs two reviews to be accepted.
What it predicts
- Markers appear throughout long sections with peaks tied to slow sedimentation or surface stability.
- Chemistry of spherules matches local or volcanic sources.
What would rule it out
- Unambiguous shock features or meteoritic isotope signatures confined to the boundary at several independent sites.
