Living in the Shadow of Zonolite Mountain

, 2008
Much of what is known about the environmental disaster in Libby, Montana, has been due to the unflagging efforts of residents Les Skramstad, U.S. attorney for Montana, and Gayla Benefield. In this ABC News program, these determined individuals are joined

Cytotoxicity induced by exposure to natural and synthetic tremolite asbestos: An in vitro pilot study. [PDF]

, 2012
Mineral fibers are potential carcinogens to humans. In order to help clarify the etiology of the pathological effects of asbestos, cellular reactions to natural and synthetic asbestos fibers were compared using a lung alveolar cancer cell line (A549 ...

Single-crystal elasticity of tremolite at high-pressure conditions and its implication for the mid-lithospheric discontinuity

, 2021
Tremolite is the calcium magnesium amphibole that widely occurs in igneous and metamorphic rocks of the crustal and upper mantle lithosphere, especially in the greenschist facies to amphibolite facies of ultramafic assemblages.

Note on rock-forming minerals in the Joetsu district, Niigata Prefecture, Japan. (13) Tremolite-actinolite from the Kotaki-Omi district.

, 1998
Actinolite-tremolite series occur in the contact between crystalline schists and serpentinite, and xenolith in serpentinite, Hisui-kyo (jadeite valley), Omi, Niigata Prefecture. Tremolite coexists with serpentine, chlorite and Cr-muscovite.

Intensity of allowed and forbidden electron spin resonance lines of Mn²⁺ in tremolite

, 1968
The angular variation of the intensities of the allowed and forbidden (Δm = ±1) electron spin resonance lines of Mn2+ impurities in tremolite, 2(H2Ca2Mg5(SiO3)8), was studied at room temperature and in the 9.2-GHz microwave frequency range.

Surface alteration mechanism and topochemistry of iron in tremolite asbestos. A step toward understanding the potential hazard of amphibole asbestos

, 2015
Non-occupational, environmental and unintentional exposure to fibrous tremolite, one of the most widespread naturally occurring asbestos, represents a potentially significant geological risk in several parts of the world.

XII. On the Tremolite of Cornwall. [PDF]

Transactions of the Geological Society of London
I do not know whether some observations upon a fossil of tlie Tremolite species, which I discovered some time since in the county of Cornwall, may be worthy the attention of the Geological Society. I was induced to record them for the following reasons. I was not aware that tremolite had ever been noticed before in our western counties.

Insights Into Subduction‐Zone Fluid‐Rock Interactions and Carbon Cycling From Magnesium Isotopes of Subducted Ophiolitic Mélanges in the Arabian‐Nubian Shield

Geochemistry, Geophysics, Geosystems
Fluid‐rock interactions play an important role in element mobilization, mass transfer, and formation of critical metals in subduction zones. However, tracking the multistage fluid‐rock interactions within subduction channels remains elusive.
