These rare calcium carbonate crystals, whose formation requires temperatures below 4 degrees Celsius, consist of the mineral Ikaite and occur in the tens of millions on the Danish islands of Fur and Mors. They were dated 56-54 million years ago.
Why we find Glendonite from a hot period with temperatures ab…
