Oxygen and hydrogen isotopic analysis of tourmaline by secondary ion mass spectrometry
… these tourmaline species (schorl, dravite, and elbaite) to construct calibration curves to correct for IMB during SIMS analysis of O and H isotopes. I have applied my technique to analyses of tourmalines from the Wollaston Group, Athabasca region, Saskatchewan to test my method, and I have …

An Overview of Tourmaline Mineralogy from Gem Tourmaline Producing Pegmatite Districts in Africa
… The results show that these tourmalines are elbaite, liddicoatite, rossmanite and schorl. Fe, Mn and Ti are the principal chromophores of the studied tourmaline. Fe is the most dominant and causes green, blue, dark-brown and black colors. Mn imparts pink and red hues. Correlations between Mn …

Role of Li and B bearing fluids in crystallization and alteration of granitic pegmatites, San Diego, California
… gem-quality minerals including euhedral quartz, elbaite tourmaline, and spodumene. Feldspars in pockets are usually altered to kaolinite. This study investigates the role that fluid-soluble elements, Li, B, Cl, and F, have in controlling the mineralogy of pegmatites and subsolidus alteration …
