Abstract

In the small Ikka Fjord in southwestern Greenland, we have studied remarkable submarine tufa columns forming over alkaline springs by abiotic precipitationof the metastable, cold-water mineral ikaite (CaCO3.6H2O)1,3. The columns, which support a rich marine life, are up to 20 m high, with annual growth of more than 50 cm. We wish to nominate the locality, which seems to be unique, for classification as a geological World Heritage Site.
