Scolecite

This specimen features scolecite, a tectosilicate mineral belonging to the zeolite group, specifically a hydrated calcium silicate. Scolecite typically forms in very soft, fibrous colloform masses and is a hydrothermal mineral, resulting from the low-temperature alteration of basalts and related rocks. It is often found in association with other zeolites.

This particular specimen originates from Thetford Mines, a city in south-central Quebec, Canada, situated within the Appalachian Mountains. Thetford Mines, known historically as the asbestos capital of Canada, is located 187 km northeast of Montreal and 79 km south of Quebec City. The area is rich in mineralogical diversity, particularly in zeolites like scolecite, which are products of the region's unique geological conditions. The former municipality of Black Lake, now incorporated into Thetford Mines, is one of the localities where such specimens have been found.

Specimens of this quality are very difficult to obtain, as they are becoming increasingly rare. The fibrous nature of scolecite makes it particularly challenging to collect without damage, and high-quality examples like this one, with intact fibres and well-preserved structure, are seldom encountered. This scarcity adds significant value and interest to the specimen.
