New Mineral Named for Seaman Museum Curator

A new mineral discovered in the Mammoth-St. Anthony mine in Arizona has been named georgerobinsonite. The mineral is named after George W. Robinson, professor of mineralogy and curator of Michigan Tech’s A. E. Seaman Mineral Museum. It is a lead chromate—a salt of chromic acid—that occurs as minute, transparent, orange-red crystals on cerussite, another lead carbonate and secondary lead mineral.
