A newly discovered mineral has been named Priscillagrewite, in honor of Priscilla Grew, professor in the [then] UMN Department of Earth & Environmental Sciences [then Geology and Geophysics] and Director of the Minnesota Geological Survey from 1986-1993.  Priscillagrewite is a garnet-structured aluminous mineral rich in zirconium and yttrium, and was discovered in pyrometamorphic rocks (rocks heated by ignition of coal seams) in the Transjordan plateau, close to Amman, Jordan.  These rocks are the source of green stone beads known from Neolithic archeological sites in the Near East.  The naming honors Priscilla Grew's contributions to metamorphic petrology and geoarcheology.
