About Amphibole SupergroupHide

Formula:

AB₂C₅((Si,Al,Ti)₈O₂₂)(OH,F,Cl,O)₂

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

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.

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.
