$20.00

For sale is a glendonite from Glendon, NSW. Glendonite is an unusual and distinctive form of calcite (CaCO3).  Glendonites started out life as crystalline masses of ikaite, a hydrous calcium carbonate mineral (CaCO3·6H2O).  Ikaite only forms in near-freezing water (~0º to 7º C) of high alkalinity, in organic-rich sediments at the sediment-water interface.

Product Description

For sale is a glendonite from Glendon, NSW. Glendonite is an unusual and distinctive form of calcite (CaCO3).  Glendonites started out life as crystalline masses of ikaite, a hydrous calcium carbonate mineral (CaCO3·6H2O).  Ikaite only forms in near-freezing water (~0º to 7º C) of high alkalinity, in organic-rich sediments at the sediment-water interface.  At warmer temperatures, ikaite is not stable, and the mineral loses its water content.  It converts to calcite.
