Nonfoliated rocks may show colored bands that reflect minute impurities in the rock, but the dominant minerals show no visible alignment. some nonfoliated textures like granoblastic or minerals that are large grained are difficult to distinguish from chemical sedimentary or plutonic igneous rocks. These rocks do not have a squished look. On the identification chart we separate the rocks by texture and refer to them as foliated or nonfoliated.
