Wisconsin Geological & Natural History Survey » Plagioclase

Nearly pure albite occurs in granitic pegmatites, some times as platy variety called "clevelandite". Plagioclase does not survive extensive weathering, generally breaking down to clay minerals. Some plagioclase, however, may occur in greywacke or arkoses formed by rapid erosion and burial of material.
