What are aphanitic and phaneritic textures, and what do they say about the way the rock formed? What will be an ideal response?
Aphanitic rocks are so fine-grained that the individual minerals are too small to be seen with the naked
eye. They form when the rate of nuclei formation exceeds the rate of crystal growth, and an aggregate
of small mineral grains forms. Phaneritic rocks are coarse-grained; the rate of growth exceeds the rate
of nuclei formation, and large mineral grains form.
