Abstract K-feldspar in rocks is commonly seen as a heterogeneous mixture of mineral species and varieties with random microstructures Most consider that observable features arise from incomplete re-equilibrations owing to slow kinetic and localized effects of aqueous fluids (catalyst) with geological environment and chemical impurities playing only a secondary role
