Description	Green to grayish green tourmaline crystals (up to 10 cm across), with distinct optical zoning, occurs with quartz, blocky albite and muscovite in the Forshammar granitic pegmatite, central Bergslagen province, Sweden. Tourmaline contains inclusions of zircon and xenotime-(Y), and it is cut by veinlets of muscovite and hydroxylbastnasite-(Ce). Microanalytical and structural data (from the rim) indicate that the tourmaline can be classified as a dravite with moderate Al-Mg disorder at the Y and Z sites. Tourmaline displays chemical zoning that reflects the distribution of Fe, Mg, Al, Ca and Na. The Mg/(Mg+Fe) value is high; it decreases from core (similar to 0.85) to intermediate zone (0.76-0.79), but increases in the rim and vein dravite (0.93). The core has the highest proportion of X-site vacancy and Al content, whereas the intermediate zone is the most enriched in Fe and Na. The rim is slightly depleted in Al and has the highest Na compared to inner zones.
