Fig. 9. Photomicrograph shows a superposed metasomatic phenomenon. After nibble albitization that produced swapped rows of albite (Ab₁', Ab₂') had ended (the possible boundaries are outlined by dashed lines), nibble replacement of K-feldspathization (K₁" and K₂") occurred between two differently oriented K-feldspars (K₁, K₂). Cross-polarized light with quartz plate. Huangshaqiao two-mica granite, Guangdong province, southern China. Scale bar = 0.1 mm.
