We present 29Si MAS NMR data for a well-ordered natural anorthite, obtained in situ at temperatures of from 25 to 500 ~ C, which follow the changes in the aluminosilicate framework through the PI-I1 structural phase transition. Pairs of peaks due to sites offset by ap-I [111] converge through the Pi
