Micropores in plagioclase

Contributions to Mineralogy and Petrology, 1975
Plagioclase feldspar is often surprisingly porous on a small scale. Pores range in size from less than 1 μm to about 40 μm, and occupy up to 2.3 % by volume. In general, the highest plagioclase porosities occur in rocks which would have had a comparatively “wet” history: normal granites and pegmatites.
