Sterryite
Named for Thomas Sterry Hunt, the very first mineralogist with the Geological Survey of Canada in Ottawa. Found at its type locality near Madoc in Ontario, Canada as a hydrothermal mineral in marble, Sterryite is also purportedly found in Russia as well. Sterryite is associated with veenite and guettardite.
