Fig. 16. K-feldspar (light gray; bottom and left side) replaces zoned and albite-twinned plagioclase (top). Rim myrmekite occurs on the border of the plagioclase against the K-feldspar. The K-feldspar and rim myrmekite transects the twinning and zonation in the plagioclase. K-feldspar bordered by rim myrmekite also replaces the interior of the zoned plagioclase crystal (left of center). Wrights Lake granodiorite, north of Wrights Lake and east of Fourth of July Flat. Thin section 173 from Loomis collection.
