* * *

Gray-blue to green, highly fibrous (asbestiform) form of the amphibole mineral riebeckite.

It has higher tensile strength than chrysotile asbestos. The major commercial source is South Africa, where it occurs in Precambrian banded-iron formations; it is also found in Australia and Bolivia.

* * *

also called  Blue Asbestos,  

      a gray-blue to leek-green, fibrous form of the amphibole mineral riebeckite. It has a greater tensile strength than chrysotile asbestos but is much less heat-resistant, fusing to black glass at relatively low temperatures. The major commercial source is South Africa, where it occurs in ironstone; it is also found in Australia and Bolivia.

      Crocidolite is often replaced by quartz, forming the chatoyant semiprecious gems tigereye and hawk's-eye.
