Cryptocrystalline microstructure
• List of rock textures • Macrocrystalline • Microcrystalline • Nanocrystalline • Rock microstructure WebAlthough many of the varietal names historically arose from the color of the mineral, current scientific naming schemes refer primarily to the microstructure of the mineral. Color is a secondary identifier for the cryptocrystalline minerals, although it is a primary identifier for the macrocrystalline varieties. [24]
