Abstract

Using

natural and synthetic samples, it was investigated which Li-containing

short-range orders can occur in Li-bearing Al-rich tourmalines. The

investigated samples have lattice parameters from a = 15.72, c = 7.07 Å to a = 15.84, c = 7.10 Å. The general tourmaline formula is XY₃Z₆(BO₃)₃[T₆O₁₈]V₃W, where the X site is usually occupied by Na, Ca or is vacant. The Y site is in such tourmalines usually occupied by Al and Li, and the Z site is only occupied by Al. The T site can be occupied by Si and by minor amounts of B and Al. The V site is usually occupied by OH and the W site by OH, O or F.
