Major issues involved in the classifi cation of the amphiboles are examined: (1) the role of (OH), Li and Fe3+, (2) the formal defi nition of a root name, (3) irreducible charge-arrangements and distinct species, (4) the use of prefi xes, (5) the principal chemical variables used in a classifi cation procedure, and (6) the use of the dominant-constituent principle. The current IMAapproved classifi cation scheme is based on the A, B and T groups of cations in the amphibole formula: AB2C5T8O22W2… CONTINUE READING
