About Riebeckite Root Name GroupHide

Formula:

◻Na₂(C²⁺₃Fe³⁺₂)(Si₈O₂₂)W₂

The riebeckite minerals are sodium amphiboles defined with ^A(Na+K+2Ca)< 0.5 apfu and 1.5 apfu < ^C(Al+Fe³⁺+2Ti) with Fe³⁺ as the dominant element in the C³⁺ position.

The individual minerals are defined by the dominant elements in the C²⁺ and W positions. The most common dominant elements in the various positions are:
C²⁺ position: Mg or Fe²⁺ dominant
W position: (OH) or F dominant

Crystal System:

Monoclinic

Member of:

Sodium Amphibole Subgroup > w(OH,F,Cl)-dominant Amphibole Group > Amphibole Supergroup

Journal of Mineralogical and Petrological Sciences, 114 (1) 33-40 doi:10.2465/jmps.181109	Chemical analyses of the amphibole were performed on JEOL JXA–8800R and JEOL JXA–8900R electron microprobes at the GSJ Laboratory, AIST. Based on the relatively high oxygen fugacity indicated by the high Fe3+/(Fe2++Fe3+) ratios (0.99–1.0) of associated aegirine and garnet (Banno and Yamada, 2012), the Fe3+/Fe2+ ratios of the amphibole were estimated using the maximum ferric method of Leake et al. (1997). Total Mn was expressed as Mn2+, because, in this way, formulae calculated using the maximum ferric method satisfied the six criteria for calculation of amphibole formulae outlined by Leake et al. (1997). The amphibole is pale yellowish green and occurs as euhedral to subhedral crystals with lengths up to 500µm.

Other InformationHide

Health Risks:

This mineral is known to be a respirable carcinogen, and is a common form of asbestos. Exposure to very dusty air or long-term exposure to low level airborne dusts containing fine fibres of the mineral 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 in many amphibolites, 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.
