About Amphibole SupergroupHide

Formula:

AB₂C₅(T₈O₂₂)W₂

A = ☐, Na, K, Ca, Pb²⁺
B = Li, Na, Mg, Fe²⁺, Mn²⁺, Ca
C = Li, Mg, Fe²⁺, Mn²⁺, Zn, Co, Ni, Al, Fe³⁺, Cr³⁺, Mn³⁺, V³⁺, Ti, Zr

W = OH,F,Cl,O

Name:

The name amphibole (Greek αμφιβολος - amphibolos meaning 'ambiguous') was used by René Just Haüy to include tremolite, actinolite, tourmaline, and hornblende. The group was so named by Haüy in allusion to the protean variety, in composition and appearance, assumed by its minerals. This term has since been applied to the whole group. (Wikipedia).

An extensive and complex group of minerals presently divided into a group/subgroup/root-name hierarchy (see group/subgroup/root-name files for the individual species). The amphibole group remains under study with the most recent, IMA-approved nomenclature being published in 2012 (Hawthorne et al., 2012, superseding Hawthorne & Oberti, 2006).

Individual members can often only be correctly identified by a combination of chemical-analytical, X-ray diffraction and spectroscopic methods.

The crystal symmetry is either monoclinic (more common) or orthorhombic.

Classification of Amphibole SupergroupHide

Amphibole C2/m structure type

The amphibole structure type with sites color-coded. M1, M2, and M3 typically host metals like Mg, Fe, Al, and Mn. M4 is usually an alkali/alkali earth metal like Ca, Na, or Li. The A site is either vacant or occupied by Na or K. The W site may be O, OH, F, or Cl. Si and Al go on the T sites. The speciation of amphiboles is quite complex and was majorly redone in 2012 by Hawthorne et al.

9		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.

Anthophyllite microprobe data are normalized to 15eK (no Na in A-site). *Fe measured as Fe2+; Fe3+ and H2O calculated by stoichiometry and site filling. Composition is nearly mid-way along the anthophyllite-gedrite join, according to Hawthorne et al., 2012. Note that the reported Mg-Fe distribution between M4 and (M1+M2+M3) here is not structurally verified, but is just a simplification based on filling the VI-coordinated smaller sites with smaller Mg first, before using larger Fe2+.

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.

Varieties of Amphibole SupergroupHide

Byssolite	A fibrous to hair-like crystal or mass of fibers frequently in the ferroactinolite-actinolite-tremolite series, but may be any amphibole species.
Clinoamphibole	A generic name for amphiboles crystallizing in the monoclinic system, e.g., hornblende, cummingtonite, grunerite, tremolite, actinolite, riebeckite, glaucophane, and arfvedsonite.
Uralite	Pseudomorphs of amphibole-group minerals, mainly actinolite, after a clinopyroxene-group mineral, mainly augite. Originally described from the Urals Region, Russia.
