About Thomsonite-CaHide

01728440014946341967235.jpg
Thomas Thomson
Formula:
NaCa2[Al5Si5O20] Β· 6H2O
Colour:
Colourless, white, light yellow, light green, pink, brown
Lustre:
Vitreous, Pearly
Hardness:
5 - 5½
Specific Gravity:
2.23 - 2.29
Crystal System:
Orthorhombic
Name:
Renamed in 1820 by Henry James Brooke in honor of Thomas Thomson [April 12, 1773 Crieff, Perthshire, Scotland - July 2, 1852 Kilmun, Argyleshire, Scotland], professor of chemistry at the University of Glasgow. Thomson was an indefatigable mineral chemist and contributed enormously to the number of accurate chemical analyses of minerals during his career as well as having discovered many new mineral species. The suffix -Ca denotes the dominance of calcium in the mineral.
Zeolite Group.
The calcium analogue of Thomsonite-Sr.

Some habits may be confused with stellerite.

A potential Mg analogue may be present at this locality: https://www.mindat.org/loc-414057.html
