Fig. 27. Zoned plagioclase crystal (light gray, left side; light gray and cream, lower right side) is fractured and penetrated by K-feldspar (black, right side) which also extends into the plagioclase in rectangular islands along a plagioclase zone-band. Myrmekite occurs on right side of K-feldspar but barely visible. Outermost facies, Criffell pluton.
