Ion-microprobe analyses of Li and B in topaz show a range of four orders of magnitude for Li and three orders of magnitude for B and vary as a function of association. High-Li topaz correlates with rhyolitic and other igneous associations and low-Li topaz with hydrothermal or pegmatitic rocks. B is generally higher in igneous topaz but overlaps with analyses from other associations.-J.A.Z.
