What is moler?

Imerys moler

Moler is a unique clay-like form of diatomite, dating back to the early Eocene time, typically comprising two-thirds diatom algae shells and one-third smectite clay.
Typical moler contains up over hundred different diatoms, which are essentially round, triangular and ball shaped.


The only true deposits of moler are located on the islands of Fur, Mors and Nordsalling, off the northwestern coast of Denmark, where they were formed over fifty million years ago.
