About Thomsonite SubgroupHide

Thomas Thomson

Member of:

Zeolite Group

Name:

The root name 'thomsonite' is in honour of Thomas Thomson (12 April 1773, Crieff, Perthshire, Scotland – 2 July 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 large majority of "thomsonite" is thomsonite-Ca.
