Fractionated gas condensates from an unidentified volcanic eruption, probably an Icelandic subglacial or submarine fissure eruption.

**Still possible** Answers **1** questionPublished0

## Where it stands

**Still possible** Its tests haven't settled it: two pieces of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- Volcanic gas condensates with a matching platinum-group pattern exist.
- Tephra or sulphate from the eruption appear in the spike interval in other Greenland cores.

## What would rule it out

- Meteoritic osmium isotope ratios in the spike interval.

## Evidence 2 for · 1 against

[Modern Pt spikes in ice and sediment are known from eruptions.](https://mysteriesdept.com/mysteries/younger-dryas-impact/evidence/EVD0D51XK2A692F/modern-pt-spikes-in-ice-and-sediment-are-known-from)
