EPA 2014c), was the site of a former mine that produced vermiculite contaminated with a mixture of asbestiform
amphiboles, including winchite, richterite, and tremolite asbestos (Meeker et al.
141, states: "Asbestos means the asbestiform
varieties of serpentinite (chrysotile), riebeckite (crocidolite), cummingtonite-grunerite, anthophyllite, and actinolite-tremolite.
On the northern end of the body asbestiform
serpentine is also noted which imparts a fibrous appearance to the rock (Khan and Humayoun, 1980).
The serpentine group contains a single asbestiform
variety: chrysotile, which comprises over 90% of the asbestos mined worldwide today (Craighead & Mossman, 1982).
where vermiculite containing asbestiform
amphiboles were mined from 1920 to 1990 and given free of charge for insulation and to build driveways and ball fields.
NSSGA also has recommended expansion of the definition of asbestos to include other asbestiform
Asbestos-related disease associated with exposure to asbestiform
Data on the geographic distributions of cancers may suggest a natural component of soil (as in the case of some asbestiform
minerals that cause mesothelioma) or the emissions from a factory.
5) Although chrysotile is a reasonably well-defined mineral (see photo 2), the other five amphibole asbestiform
fibers are difficult to identify, as their physical and chemical properties are so vastly different.
Of particular interest to this study is a hydrothermally derived assemblage composed of spessartine, rhodonite and asbestiform
Mn-rich cummingtonite (Pires, 1977).
5%], of the 439 cases evaluated may have a condition consistent with exposure to an asbestiform
