Subaqueous Deposition
Chemical Process (Liquid-phase Growth) - Under water
Required Geological Setting
Neogene and Quaternary sediments
Occurrence
Minerals formed on the seafloor. Among these minerals, ikaite, which observed as calcite pseudomorph "glendonite", deposits from carbonate-rich groundwater on the surface of seafloors. The formation temperature is less than 0 degree, and it can be an index mineral of cold circumstance.
