Grenville, Uvite ps Serendibite, Portage du Fort, Quebec

Recently, some unusual pseudomorphs of uvite after serendibite have been collected near Portage du Fort, Pontiac County, Quebec. The crystals are, generally a light blue-grey and usually have a core of serendibite. Sometimes, only a thin rim of uvite is present on the serendibite, other times the crystals are solid uvite, sometimes with a little spinel. These unusual pseudomorphs are associated with white diopside crystals and a brownish phlogopite. Unusual!

  • There are two uvite pseudomorphs after serendibite at the top of this specimen. Both of them have natural fractures through them that have been partially filled with diopside, phlogopite and a brownish, prismatic mineral that resembles a tourmaline group mineral. Interesting piece!
