A study of plagioclase zoning

2012
The zoning of plagioclase feldspars was studied with the four-axis universal stage. The composition, in terms of the extinction angle X’ʌ010, ⊥a, was measured for each zone in several crystals in each of nearly fifty rocks. The values of the extinction angles for each zone were plotted against the distance of the zone from the rim of the crystal, and ...
