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.
Geology takes the long view. It is a field, after all, in which the pace of change spans billions of years. John Lyons, however, is interested in geological events that happen at a faster rate. So the recent graduate of Michigan Tech’s PhD program in geophysics has found a compromise: he studies volcanoes.
