This study examined commercial talc deposits in the U.S. and their amphibole-asbestos content. The study found that the talc-forming environment directly influenced the amphibole and amphibole-asbestos content of the talc deposit.

Large talc districts in the U.S. have mined hydrothermal talcs that replaced dolostone. Hydrothermal talcs, created by siliceous fluids heated by magmas at Cited by: The presence of asbestiform minerals as impurities in talc and vermiculite deposits and their potential impact on human health have been a subject of study and debate for more than 40 years.

Atshan Talc Mine The Atshan talc mine (latitude 24° 15', longitude 35° 13'), is one of several talc deposits in the Hamata area of the Eastern Desert, 18 km west of the Red Sea, is the largest talc deposit in Egypt.

At Atshan the host rocks are volcanic and volcaniclastic rocks of basaltic to rhyolitic composition. The Atshan deposit occurs.

Libby, Montana, is the site of one of America's worst man-made environmental disasters. Toxic asbestos dust from the vermiculite mines that helped the town prosper for decades has killed hundreds of residents, sickening thousands more.

Not every talc deposit is contaminated with asbestos. The ones that are contaminated tend to contain tremolite or anthophyllite, both forms of amphibole asbestos, rather than chrysotile, which is the serpentine form of asbestos.

Like talc, the mineral vermiculite commonly forms alongside asbestos and asbestiform minerals. Hagner () studied the wyoming vermiculite deposits and found evi-dence for the hydrothermal origin of the vermiculite.

Thus, the origin of vermiculite deposits formed in seemingly similar environments has re-ceived different interpretations. Libby, Montana is petrologically and mineralogically one of the simplest of the vermiculite Size: 1MB.
