About Leucophoenicite Subgroup
Member of:
Name:
The Leucophoenicite Subgroup is named after the dominant member of the subgroup, which in turn are named by Samuel Lewis Penfield and Charles Hyde Warren in 1899 from the Greek for λευκοσ "pale" and φοινιζ "purplish red" in allusion to its common color.
The leucophoenicite Subgroup minerals are unit cell-twinned polymorphs of the corresponding humite-group minerals.
The minerals in this series form a polysomatic series where the individual species are defined by the number of olivine-type layers (n) between each norbergite-type layer (Mg(OH,F)2). Ribbeite (n = 2) and jerrygibbsite (n = 4) have an orthorhombic symmetry, whereas leucophoenicite (n = 3) is monoclinic.
