Fig. 4. Photomicrograph of granite containing microcline (grid-twinned; gray), plagioclase (albite-twinned; tan, gray, white), myrmekite (attached to plagioclase and projecting into microcline), quartz (white, gray, cream, tan), and biotite (brown). Texture is hypidiomorphic and has the appearance of being crystallized from a magma. Most microcline grains (not shown in photo) lack myrmekite borders. From granite dike about 3 meters northwest of photo 7 in Fig. 3.
