Experimental animal studies comparing asbestos and non-asbestos varieties of tremolite indicate tremolite asbestos is markedly more carcinogenic. By direct analogy, the differences in carcinogenicity ...
We report here an investigation of amphibole synthesis within the ternary system Ca Mg Si O (OH) - Mg Al Si O (OH) -Mg Si O (OH) (= TR-PG-MC) to define better the limits of solid solution for amphi...
A magic-angle-spinning nuclear magnetic resonance (MAS NMR) spectroscopic study was done on the series of synthetic gallian-fluor amphiboles to identify the extent of Ga and Si ordering in the Si MA...
