Formula:

A_0-1Na₂(C²⁺_2-4C³⁺_1-2Li_0-1)_Σ5(Si_8-mAl_mO₂₂)(OH,F,Cl)₂

The sodium amphibole subgroup is one of the subgroups belonging to the W(OH,F,Cl) amphibole group. It is defined with Na as the dominant element in the B position.
(The IMA-CNMNC definition is ^B(Na + Li)/ΣB ≥ 0.75, ^BNa/ΣB ≥ ^BLi/ΣB)

The sodium amphibole subgroup are further divided into root-name groups that are defined by the charge balance and dominant elements in the A and C positions in the generic formula above. The various positions in the formula can have the following content:

A position: n=0 or 1, when 1, it contains Na or K as the dominant elements.

C position : For all root name groups except the Nybøite and Leakeite groups, the content in the C position is C²⁺_3+nC³⁺_2-n, and with Si₈ in the T position.

The Nybøite group has n=1 and C²⁺_3+n C³⁺₂, balancing the formula with m=1 in the T position.

The leakeite group contains Li in the C position and it's C position is defined with C²⁺₂ C³⁺₂Li.

Mg, Fe²⁺, Al and Fe³⁺ are normally the dominant elements in the C²⁺ and C³⁺ positions for all root name groups.

(OH), F or Cl dominance define mineral species within a root name group.

Member of:

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

Name:

This amphibole subgroup was named "Alkali-amphiboles" in Leake's "Nomenclature of amphiboles"(1978) and renamed as "Sodic amphiboles" in the 1997 amphibole nomenclature. The group was again renamed in the 2012 amphibole nomenclature to "sodium amphibole subgroup".

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.
17		Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada		The analyses were perfromed on fragments of ferro-ferri-nybøite that were ground with an agate mortar and pestle, placed on a Pb ring (2 mm inner diameter), and secured in place with tape. EMPA was perfromed with a Cameca SX-100 operating in the wavelength-dispersive mode with an excitation voltage of 15 kV, specimen current 10 nA, beam diameter 5 μm, peak-count time 20 s, and background-count time 10 s. The Mössbauer spectrum was acquired in transmission geometry at room temperature using a 57Co(Rh) point source, and the spectrometer was calibrated with the room-temperature spectrum of α-Fe. The spectrum was analyzed in terms of a Voigt-function-based quadrupole-splitting distribution. The XRD powder-diffraction pattern was recorded using a D5000 Bruker powder diffractometer (Ni-filtered CuKα radiation, λ = 1.54178 Å). No internal standard was used.
