- •
We have further shown the presence of celestite in bone fossils of Molì del Barò-1 site.
- •
The XRF measurements, confirming the XRD analysis, are compatible with a partial substitution of divalent ions of Sr with Ba.
- •
The marine influence on this site is undeniable and has led to a successful upgrade of the previous stratigraphy.
- •
The transport mechanism of solutions celestite/barite may exist over long distances in underground fluid environments.
