Plagioclase crystallisation in a granodioritic melt and its petrogenetic implications for the origin of the A‐type granite in East Junggar, NW China

Crystallisation experiments were performed on a natural I‐type granodiorite from East Junggar of Xinjiang, NW China, at 1.0 and 1.5 GPa in the temperature range between 700 and 875 °C and for various water contents to investigate the crystallisation behaviour of plagioclase in granodioritic melts. Experimental results indicate that the optimal conditions for plagioclase to crystallise in this granodioritic melt are approximately 875 °C, 1.0 GPa,...
