The mineral terms “biopyribole” and “pyribole” were coined by A. Johannsen from parts of the names (bio)tite, (pyr)oxene, and amphi(bole) as labels to be used in the field when more precise identification was not immediately possible. These terms were revived by J. B. Thompson, Jr., for crystallochemical reasons to illustrate the kinship among micas, pyroxenes, and amphiboles.
By dividing the structures of these mineral groups into modules (see Polysomatism), the amphibole structure and composition may be conceived as a mineralogical hybred composed of alternating modules of pyroxene and mica structures and compositions in the ratio 1:1 (see Table 1).
