|  Serandite is the manganese analog of pectolite, and occurs in various 
      shades of pink to orange. It occurs as large well formed triclinic crystals. 
      It is of great interest to collectors because of its beauty, but has no 
      industrial value. The Demix Quarry at Mont St. Hilaire was opened in 1961 
      to mine nepheline syenite for use as an aggregate in concrete. In 1962, 
      Frank Melanson, a salesman for a paper products company, discovered beautiful 
      but unfamiliar minerals in the quarry. A number were identified including 
      catapleiite, monteregianite, acmite, synchysite, narsarsukite, and serandite. 
      In 1973, Rolland Bouhelier dug into a pipe-like vug and discovered an incredible 
      array of serandite crystals each studded with snow-white analcime crystals. 
      This specimen in the UCSB Geology Collection is one of the best-known miniature 
      specimens (five by three centimeters).  |
