| Summary: | Ikaite, found as a constituent of tufa chimneys and mounds in Ikka Fjord, Greenland, is only formed in waters close to freezing point. At higher temperatures it inverts to calcite, forming impressive pseudomorphs which have been found at a large number of locations world‐wide of varying ages, sometimes in association with glacial deposits. The Ikka Fjord deposits, first described by the Danish geologist Hans Pauly, were key to understanding the nature of these widely reported pseudomorphs. |
