Chrysotile asbestos was discovered in 1946 about 10 miles west of Mbabane, Swaziland. The asbestos fiber occurs in narrow mylonitized pale green bands of serpentinite occurring in dark blue-green serpentinite. The deposit appears to have resulted from fault or shear action, and while it is not of economic grade, deposits of economic importance may be found which were formed under comparable conditions elsewhere.
