The formation of asbestiform amphiboles must result from multiple nucleation and specific growth conditions.
Of the amphiboles, only a few varieties have an asbestiform habit and the latter occur in relatively low quantities.
The difference between asbestiform and massive amphibole minerals is obvious on the macroscopic scale, although the crystalline structures of the two varieties do not exhibit substantial differences.
The asbestiform amphiboles tend to have a larger number of crystal defects (Wadsley defects and twinning and chain-width disorder) than the nonasbestiform varieties.
However, the statistical average of their aspect ratio is considerably lower than that of the asbestiform amphiboles.
Libby vermiculite is contaminated with an especially toxic form of naturally-occurring asbestos called tremolite-actinolite asbestiform mineral fibers.
Excess risk of pleural mesothelioma from past exposures to asbestos, as evidenced by a trend of high incidence rates during the last half century, appears to be the result of nonchrysotile asbestiform fibers.
