Minerals Jeffrey Mine, Asbestos

The Jeffrey mine was located in the heart of the ophiolitic complex that crosses Estrie and Beauce, a band of mafic and ultramafic rocks. A real shred of the oceanic lithosphere that existed under the Iapetus Ocean about 550 million years ago. Ophiolites are generally formed from marine sediments, pillow basalts, intrusive gabbros and diabases, and other ultramafic rocks of the Earth's upper mantle. Dykes (or veins) formed in parts of the deposit. It is in these veins that we find the exceptional crystallizations of grossulars and vesuvianites. The site was closed in 2012.
