About Amphibole Supergroup
Formula:
AX2Z5((Si,Al,Ti)8O22)(OH,F,Cl,O)2
A = ☐, Na, K, Ca, Pb2+
X = Li, Na, Mg, Fe2+, Mn2+, Ca
Z = Li, Na, Mg, Fe2+, Mn2+, Zn, Co, Ni, Al, Fe3+, Cr3+, Mn3+, V3+, Ti, Zr
The IMA nomenclature report (Hawthorne et al., 2012) uses the general formula AB2C5T8W2. On mindat.org we avoid using variables with the same symbol as elements and we use X rather than B, Z rather than C and (OH,F,Cl,O) rather than W.

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.
