Anthophyllite Asbestos

Similarly to tremolite asbestos, this type was not commercially used in the U.S. either and would often be encountered as a contaminant. It is primarily found in Finland, but small deposits also occur in North Carolina and Georgia. The fibers of anthophyllite asbestos can be white, gray or brown and generally develop in large, shapeless bundles. With a high content of iron, magnesium, and silicon, anthophyllite asbestos forms on metamorphic and metasomatic rocks.

Also known as azbolen asbestos, this mineral was mined in Japan as well. Between 1883 and 1970, a large-scale open-cast asbestos mine and mill was operating in the former Matsubase town. The anthophyllite asbestos from the two Finnish mines was added in roofing materials, cement, and insulating products outside of the U.S. until 1975.

The Most Common Uses of Anthophyllite Asbestos

Anthophyllite asbestos may be present as a contaminant in the following products:

• talcum powder
• composite flooring
• vermiculite products

However, since asbestos regulations are effective nowadays, the risk of encountering this carcinogen in the products you purchase is extremely low. If you house has vermiculite attic insulation, we strongly encourage you to have it removed by a professional asbestos abatement company, as exposure is very likely to occur. The majority of vermiculite insulation manufactured before the 1980s contained high amounts of asbestos, since deposits are often found very close to each other in the earth and the refining process was not very efficient in removing the toxic mineral.
