chrysotile

I found there, however, a piece of unmistakable chrysotile, grouped amongst a miscellaneous lot of American minerals.

Crocidolite or blue asbestos is similar to chrysotile but somewhat inferior in fire-resisting qualities.

In Arizona chrysotile is found in veins in cherty limestone, associated with diabase intrusives.

Asbestos consists mostly of magnesium silicate minerals—chrysotile, anthophyllite, and crocidolite.

Mineralogically it is distinct from chrysotile, which is used for similar purposes.
