About Fluoro-edeniteHide

Formula:

NaCa₂Mg₅(Si₇Al)O₂₂F₂

The minerals in the edenite group is defined with ^A(Na+K+2Ca)≥0.5 apfu) and ^C(Al+Fe³⁺+2Ti)≤0.5 apfu and with (OH), F or Cl in the W position.

Fluoro-edenite is defined with
A position: Na dominant
C position: Mg dominant
W position: F dominant

Colour:

Light green to light yellow, grey-black

Lustre:

Vitreous

Hardness:

5 - 6

Specific Gravity:

3.09 (Calculated)

Crystal System:

Monoclinic

Member of:

Edenite Root Name Group > Calcium Amphibole Subgroup > w(OH, F, Cl)-dominant Amphibole Group > Amphibole Supergroup

Name:

Fluoredenite was originally known as a synthetic compound and reported as early as 1955 by J. A. Kohn and J. E. Comeforo. In 1970, Dr. Bob Coffee, chemist at Kodak, chemically analysed and published on one an early discovery of non-synthetic fluoredenite. Named fluoro-edenite in 2001 by A. Gianfagna and R. Oberti following IMA rules in allusion to its composition, with dominant fluorine and its relationship to edenite.

Type Locality:

ⓘ Mt Calvario, Biancavilla, Metropolitan City of Catania, Sicily, Italy

Other InformationHide

IR Spectrum:

The IR spectrum does not show any absorption band in the OH-stretching region (3800–3600 cm–1). In the 1300–450 cm–1 range, significant absorption bands occur at 1066, 991, 791, 738, 667, 517, and 475 cm–1.

Health Risks:

This mineral is known to be a respirable carcinogen, similar to asbestos and many other amphiboles, and exposure to very dusty air or long-term exposure to low level airborne dusts containing fine fibres of fluoro-edenite and related amphiboles has been found to cause a high risk of serious lung disease including mesothelioma and lung cancer. Care should be taken working with samples that contain fibrous forms of this mineral, to avoid creating or inhaling dusts. Non-fibrous forms, such as larger crystals or rock samples containing solid grains, are safer to handle, but can still produce potentially carcinogenic respirable fibre when crushed. Appropriate dust masks should be worn if working in areas which have dusts likely to be rich in this mineral. Storage and careful handling of specimens has little or no risk.
