⤱ Glendonite ⤱

Glendonites are a pseudomorph of calcite, formula CaCO3, after the mineral ikaite, formula CaCO3.6H2O. They are thought to have formed in glacial conditions. More information on glendonites can be found here.

This is a particularly large specimen (albeit repaired) from the Hunter Valley in New South Wales.
