have been found in southern Finland (pargasite, potassium pargasite, Fe-hornblende and actinolite), but their lattice parameters differ from those of Lemme amphiboles
Lung burdens of talc and its amphibole
contaminants are markers of exposure to talc-containing dusts.
in scapolite metagabbros were produced during fluid infiltration into the dry protolith gabbro [20, 29].
Amphibolite contains a lot of metamorphic minerals such as biotite and amphibole
. In this connection, it is interesting to find out how a varying degree of metamorphic reworking affects the physical properties of rocks.
IMA report--Nomenclature of the amphibole
Although the predominant part of asbestos used in East Germany was chrysotile asbestos and amphiboles
were hardly used in East Germany, some participants might have been exposed to amphiboles
that might be responsible for some of the observed effects.
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.
Kaersutite and pargasite are amphiboles
typical of alkaline basic rocks and metasomatised mantle xenoliths and their formation occurs early during the crystallization process (e.g.
The classification of amphiboles
is based on the composition of the standard amphibole
formula [AB.sub.2] [sup.IV][C.sub.5][sup.IV][T.sub.8][[O.sub.2].sub.2] [(OH).sub.2].
The vermiculite was contaminated with various fibrous minerals known as amphiboles
, including two types of asbestos.
Brownfield et al., "The composition and morphology of amphiboles
from the Rainy Creek complex, near Libby, Montana," American Mineralogist, vol.
The greater pathogenicity associated with amphiboles
is attributed to the rigidity of its fibers more likely to be more aerodynamic and deposit in the gas exchange regions of the lungs where many penetrate the pulmonary intersti-tium.
These clasts are essentially ophiolitic consisting of serpentine, olivine, pyroxenes, plagioclase and amphiboles
with minor of cherty made up of microquartz and mega quartz.
