For my last post I figured I would make it the best one yet…Norris hite!! Yes they named a mineral after Chuck himself(not really actually it was named after Keith Norrish from the Commonwealth Scientific and Industrial Research Organization, Australia.) Norrishite[K(Mn2Li)Si4O10(O)2] is a manganiferous schist, formed through metamorphism of a manganese deposit. It’s found mostly in Australia and has perfect cleavage. It is brownish black to black, is translucent, and has a hardness of 2.5. It’s biaxial and is radioactive, but it is barely detectable.
