Fig. 8. Photomicrograph of aggregate myrmekite grains with tiny quartz vermicules (lower left) bordering K-feldspar (gray, upper right) in the granodiorite sub-facies of the Sharpners Pond biotite tonalite. Remnants of larger albite-twinned plagioclase crystals occur as inclusions in the K-feldspar and have optical continuity with each other.
