German Chrysotil, from chrys- + -til fiber, from Greek tillein to pluck
First Known Use: 1850
Fibrous variety of the magnesium silicate mineral serpentine; it is the most important asbestos mineral. Individual fibres are white and silky, but the aggregate in veins is usually green or yellowish. Chrysotile fibres have a high tensile strength, similar to that of other asbestos minerals (seeamphibole asbestos). The largest deposits of chrysotile are in Quebec and in the Ural Mountains.
