Comments:Perthitic and non-perthitic microcline is the main feldspar. Coarse crystals and blebs of perthite are also seen within the quartz cores near their margins. Coarse-grained feldspar lenses are cut by irregular masses of grey quartz, which themselves contain subhedral perthitic crystals. The inner parts of the intermediate zones of several zoned pegmatites consist almost entirely of perthite, whereas,
the outer parts comprise intergrowths of quartz, feldspar, and muscovite and occasionally biotite.
