spinel - Opis:
- Samples of boundary clay from Cretaceous–Paleogene deposits from Lechówka, Poland were examined for spherules to confirm the impact origin of the sediment. The chemical composition of investigated spherules show similarities to material from the K–Pg boundary from Stevns Klint. The impact genesis of the spherules is confirmed by the presence of nickel-rich spinel grains on their surfaces. The deposits with spherules are built by smectite with Al and Mg enrichment. This cheto smectite is forming as a result of the weathering of the impact glass.
