Akermanite from Oka, Quebec, Canada – miniature specimen as unique piece
This specimen displays a dense, fine-grained formation of Akermanite in bluish-grey to nearly black tones. The surface appears compact with a subtle sheen. Slight color variations throughout the material suggest the presence of additional paragenetic minerals, adding structural interest to the piece.
Akermanite belongs to the sorosilicate group and is a typical high-temperature mineral found in contact metamorphic skarn deposits. It forms under the influence of magmatic fluids reacting with silicate-rich and carbonate rocks. Massive aggregates like this are of particular relevance for petrological studies and systematic collections.
Geology & Origin:
The region around Oka in the province of Quebec is well known for its alkaline rock complex, rich in rare silicates and carbonates. In the associated carbonatite and skarn zones, Akermanite frequently occurs in compact masses. Specimens from this locality are highly regarded among collectors and mineralogists alike.
