Mo-Clay cliffs at Knudekilerne. Island of Fur, Denmark.
Mo-Clay cliffs at Knudekilerne. Island of Fur, Denmark. The island of Fur is in particular known for it's large deposits of Mo-Clay - or Diatomaceous earth - which is a highly porous rock formation and is used for special high heat insulation purposes and many other industrial and house hold purposes. The Mo-Clay layers was formed for some 55 million years ago by diatoms deposits which filled the sea which covered Denmark. The dark layers are ash from volcanic eruption. Ash clouds was by wind blown out over the sea where it landed on the water and finally layered at the seabed. As time passed a layer of diatoms was deposit over the ash. And so on. The mo-clay formation, like the one on the photo, may have up to 200 layers of ash, of which 179 has been numbered. Mo-Clay (the word comes from the Danish: Mo-clay) consist of 10% ash, 30% clay and 60% diatom-shells and is on Fur subject to large, commercial open pit mining. Mo-Clay also have many fossils, both animals, birds, fish and plants - and fossil hunting is very popular among tourists visiting Fur.
