• Ikaite - Wikipedia

    en.wikipedia.org/wiki/Ikaite Ikaite is the mineral name for the hexahydrate of calcium carbonate, CaCO 3 ·6H 2 O. Ikaite tends to form very steep or spiky pyramidal crystals, often radially arranged, of varied sizes from thumbnail size aggregates to gigantic salient spurs. It is only found in a metastable state and decomposes rapidly by losing most of its water content once removed from near-freezing water.

  • Mapping The Ikaite Columns Of The Ikka Fjord, SW

    www.marinetechnologynews.com/news/mapping-ikaite-columns-fjord-599723 Ikaite is found in areas outside of the Fjord, generally in sediments where an identified calcite inhibitor exists facilitating the formation of Ikaite meaning its presence can be explained. Without an inhibitor common calcite, not ikaite would otherwise form. In recent years ikaite has been found forming in Arctic and Antarctic sea ice.

Although calcium carbonate is normally found in the anhydrous form as calcite, aragonite or (occasionally) vaterite, J.F. Daniell made the first hydrated calcium carbonate in 1819 and Pelouze showed this to be the hexahydrate in 1831 .However, the mineral form of CaCO 3 · 6H 2 O was not discovered until 1963, in the Ika fjord in 1963 in southern Greenland, and ...

As a result of its restricted conditions of formation it is a worldwide rarely documented carbonate mineral – in particular from the continental ...
