Biological effects of tremolite [PDF]
British Journal of Cancer, 1982 Tremolite is an amphibole which has been implicated in a variety of disease patterns in different parts of the world. It occurs in a number of phases, which are chemically identical but have specific physical characteristics. In an attempt to clarify the epidemiological findings, tremolite fibres of 3 specific forms--A, B and C--were characterized and ...

Chemical and structural characterization of fibrous richterite with high environmental and health relevance from Libby, Montana (USA) [PDF]
, 2016 This study reports new structural and spectroscopic data of a sample of fibrous richterite from Libby, Montana (USA). The OH-stretching region was investigated by FT-IR. The spectrum showed, except for the typical absorption band at 3671 cm-1 assigned to

Micro-morphology and Mineral Composition of Different Color Qinghai Nephrites
Yankuang ceshi, 2018 BACKGROUND Qinghai nephrites show different colors. In recent years, there have been a lot of studies on Qinghai nephrite mineralogy, but the studies on the mineral characteristics of Qinghai nephrite with different colors are lacking.

Physics and Chemistry of Minerals, 2000 Powder IR spectra of synthetic richterite-tremolite and Sr-tremolite-tremolite solid solutions were obtained in the spectral range between 1400 and 600 cm−1. Under the consideration of the crystal structure and the Wykoff positions of the atoms in the primitive unit cell, the number, type and symmetry of vibrational modes were deduced.
