Question

Quizplus · Accepted Answer

Aphanitic textures are characterized by mineral grains that are so small they cannot be seen with the naked eye and require magnification to be observed. This is in contrast to phaneritic textures, where mineral grains are large enough to be seen without magnification. Pegmatitic textures have exceptionally large crystals, and porphyritic textures feature large crystals embedded in a finer-grained matrix.
