Mbssbauer and near-infrared spectral measurements have been made on several tourmaline minerals representing both the elbaite-schorl and dravite-schorl series. The specimens were characterized by cell dimension measurements, and by partial chemical analyses by electron microprobe. M'ssbauer data for the iron-bearing specimens further substantiated the presence of ferrous and ferric cations in b...
