Serandite

Serandite is an hydrous silicate of manganese, calcium and sodium identified by the French geologist A. Lacroix in the Island of Rouma, Los Islands, Guinea in 1931. The name was given in honor of J.M. Serand, a mineral collector. The serandite from Los Islands was powder size.

Later it was identified in other parts of the world in alkaline complex as in Brazil and Australia.

In the early 1960's serandite was found in the alkaline complex of Mont St-Hilaire, Quebec, Canada. known as the Poudrette Quarry. It was considered as a fantastic discovery in the mineral collector kingdom. Prismatic crystals of serandite up to 10 cm or more, salmon pink to light pink, translucent and with a greasy aspect hit the market. They were associated with natrolite, white to transparent analcime, aegyrine, nepheline and albite and sometimes with eudyalite or with other rares minerals. Serandite is like Pectolite but it contains manganese. Read More...
