A mineral is named after former State Geologist Priscilla Grew!

Priscillagrewite-(Y), ideally (Ca2Y)Zr2Al3O12, is a garnet discovered by Irina Galuskina and her colleagues in 2020, from an exposure of marble in Jordan. It is the eighth new garnet species discovered by Galuskina. 

It is named for Priscilla Grew, who has held several posts, including State Geologist of Minnesota from 1986 to 1993. As Priscilla P. Dudley, she was first to reveal oscillatory zoning in eclogitic garnet using scanning electron beam photography; hence the nickname “the garnet lady” that she shares with Galuskina. Grew’s mother introduced her to collecting minerals in 1947 when Grew was only seven and the family was on vacation in Colorado. 

Congratulations, Priscilla!
