Cumulative frequency curves of K-white mica b cell dimension. Solid line 1 Bosos low pressure type, solid line 2 N. New Hampshire low intermediate pressure type, solid line 3 Otago intermediate high pressure type, solid line 4 Sanbagawa high pressure type, shaded line represents the cumulative frequency curves of K-white mica b cell dimensions from HA and A-E transition (5,470–7,000 m)
