Where to find Chrysotile Asbestos
Canada (Quebec)
Historically one of the largest producers, particularly in the Thetford Mines and Asbestos (now Val-des-Sources) regions, associated with large serpentinite bodies.
Russia (Ural Mountains)
Significant deposits, particularly in the Bazhenovskoye deposit, associated with large ultramafic massifs.
Kazakhstan
Major chrysotile deposits, often associated with ophiolite complexes.
Brazil
Deposits in the Cana Brava region, associated with serpentinized ultramafic rocks.
Zimbabwe
Historically important deposits, often found in greenstone belts associated with serpentinized komatiites.
USA (California, Vermont, Arizona)
Smaller, historically significant deposits, often in serpentinite belts.
Collecting tips
- Safety First. NEVER attempt to collect or handle chrysotile asbestos without proper personal protective equipment (PPE) and specialized training. Inhalation of asbestos fibers can cause severe and fatal lung diseases, including asbestosis, lung cancer, and mesothelioma. Leave identification and removal to trained professionals.
- Geological Context. Chrysotile is typically found in association with serpentinite, a metamorphic rock that is often green, black, or mottled. Look for fibrous veins or masses within these rocks.
- Visual Identification (from a distance). If observed in situ, chrysotile may appear as white, grayish, or pale green fibrous material with a silky luster, often within cracks or veins in serpentinite. Do not disturb or touch.
- Professional Assessment. If you suspect you have found chrysotile asbestos in a natural outcrop or in a building material, do not disturb it. Contact a qualified geologist or environmental consultant for professional assessment and safe handling procedures.
