## Abstract Plagioclase crystals Ab~20~An~00~ and nearly pure anorthite were grown on the surface of artificial melts by hydrothermal treatment at 2 kb. The average crystal size was 0.002 to 0.008 mm. In the temperature range of 400Β° to 600Β°C a pseudohexagonal habit was observed for anorthite while
