phenocryst

/ ´Úŧ′²ÔÉ™-°ì°ùÄ­²õ³Ù′ /

  1. A large crystal that is surrounded by a finer-grained matrix in an igneous rock. Phenocrysts are usually the first crystals to form from a cooling magma, and therefore have sufficient room to grow to a large size. They are analogous to porphyroblasts in metamorphic rock.
