asbestization

In view of the likely meteoric origin of the asbestizing solutions and the progressive character of the asbestization, it would appear best to interpret the relationship of economic chrysotile deposits to geological events around dunite-harzburgite intrusions (gabbro or granite injection, vertical or horizontal replacement of the bodies, and so) as related to activation of hydrothermal solutions of meteoric origin.

[…]penetrated the interiors of the ultramafite rocks through numerous smaller cracks and fissures and acted as the cause of allometamorphic serpentinization and asbestization.[…]The formation of chrysotile-asbestos deposits without the corresponding process of serpentinization is impossible, and chrysotile-asbestization represents one of the stages of the hydrothermal metamorphic process of ultramafites.
