phaneritic
This term is a specialized geological descriptor used primarily in petrology to categorize igneous rocks. It describes a texture where the mineral grains are visible to the naked eye, which serves as a diagnostic indicator that the magma cooled slowly deep underground (intrusive), allowing crystals ample time to grow.
It stands in direct contrast to aphanitic texture, where crystals are too small to be seen without magnification. Because it is a technical scientific term, it is almost exclusively found in academic papers, geological surveys, and textbooks rather than in general conversation.
