Thomsenolite is a mineral with formula: NaCaAlF 6 ·H 2 O. It is an alteration product of cryolite.. It was discovered in 1868 in Ivigtut, Greenland and named for Hans Peter Jorgen Julius Thomsen (1826–1909).. References
Thomsenolite is a relatively rare mineral, known most notably from Ivigtut, Greenland (type locality) and also from lesser-known occurrences in Colorado, Utah, Norway, Ukraine, Russia and Nigeria. Thomsenolite was found in a very unusual mineral assemblage in the contact zone of the sill, consisting of leached cryolite and cellular masses of ...
Thomsenolite definition is - a mineral NaCaAlF6.H2O consisting of a hydrous fluoride of aluminum, calcium, and sodium and occurring in small white prismatic monoclinic crystals on cryolite.

Thomsenolite, a monoclinic pseudo-cubic mineral, has a nearly square cross section when viewed down the c axis. The cubic appearance is here enhanced by the ocher iron stain. Thomsenolite can be distinguished from its dimorph, pachnolite, which, when viewed down the c axis, has a noticeable less square cross section. Study specimens were ...
