Fig. 37. Interior replacement of plagioclase (tan) by microcline (gray). The albite twinning of the grid-twinning in the microcline is in parallel alignment with the albite twinning of the plagioclase. Surrounding groundmass minerals show slight cataclasis and granulation. Note that this figure is from site 36 on Fig. 2 until Fig. 2 can be corrected.
