1.7" Hematite Crystals in Lizardite & Hydrotalcite - Norway
This is a 1.7" wide specimen that contains hematite crystals (pseudomorph after Ilmenite) that are partially encased by a lizardite (yellow-green) and hydrotalcite (white) matrix. This beautiful specimen was collected from the Øvre Dypingdal Mine (Dypingdal Serpentine-magnesite deposit) of Buskerud, Norway.
Hematite is a fairly common mineral, typically responsible for the red-brown coloration that can be found in other minerals and rocks. The chemical composition of hematite is Fe2O3, occasionally containing small amounts of titanium (variable formula (Fe,Ti)2O3). Much of the time, non-crystalline hematite specimens are the result of a transformation from limonite following loss of water.
