Extract

The rare mineral stichtite, a complex hydroxy-carbonate of magnesium, chromium, and iron, was defined in 1910 by W. F. Petterd on material from the Adelaide silver-lead mine, Dundas, Tasmania. Petterd's description, together with detailed optical and chemical studies by A. S. Wesley, L. K. Ward, L. Hezner, and A. Himmelbauer, were collected by W. H. Twelvetrees and issued by the Tasmanian Department of Mines in 1914. A new analysis of the Tasmanian material is included by W. F. Foshag in his investigation of the hydrotalcite group.

The mineral was next recorded by E. Poitevin and R. P. D. Graham from the Megantic mine, Black Lake area, Quebec; no chemical data of this occurrence are available.
