Characteristics of Tourmalines from Nanping Granitic Pegmatites in oft-com:office:smarttags" />
Tourmaline is a kind of accessory mineral widely distributed in acidic igneous rocks and metasomatites, and the most widely distributed Fe-Mg-Li tourmaline includes several end members like dravite, schorl and elbaite as well as a series of transitional minerals. Based on detailed descriptions of physical-optical characteristics, chemical components, X-ray powder diffractions, infrared absorption spectra and thermal spectra of tourmalines from Nanping pegmatites, this paper discusses the evolution regularity and formation environment of these tourmalines. oft-com:office:office" />
