The lower, dark grey layer is melilite/nephelinite ash. The thicker layer above is phonolitic pumice (452 ka).

---

The lower layer is glacial loess. The following, thin grey layer is pumice (~465 ka) and a layer of ash that has been fluvially reworked. The darkest layer (quite thick) is melilite ash; contains olivine.
