摘要：
We have synthesized large (0.7-1.0 mm) crystals of anhydrous, water-bearing, and Fe-bearing wadsleyite by means of growth from solution in the thermal gradient field. Nearly anhydrous (<68 +/- 4 wt ppm H2O) Mg2SiO4 crystals were grown using K2Mg(CO3)(2) as a solvent at 16.5 GPa and 1700 degrees C. (Mg0.92Fe0.08)(2)SiO4 crystals containing 84 +/- 17 wt ppm H2O were grown using 92K(2)Mg(CO3)(2)-8FeCl(2) as a solvent. Crystals of Fe-free wadsleyite with 1496 +/- 117 wt ppm H2O were synthesized at 1400 degrees C and 15.5 CiPa by using 2KHCO(3)-Mg(OH)(2) as a solvent.
