Fig. 8. Several plagioclase crystals are partly nibbly replaced by K-feldspar. The remnant islands of unreplaced plagioclase are in parallel optical continuity with the larger plagioclase crystal nearby. The local parts of K-feldspar with remnants of plagioclase are nibbly formed, but those parts lacking remnants acted as substrate on which the nibbly replacing K-feldspar grew towards the disoriented plagioclase. Cross-polarized light with quartz plate. Huangshaqiao two-mica granite, Guangdong province, southern China. Scale bar = 0.1 mm.
