Marble is non-foliated.Foliated rocks and nonfoliated rocks are two types of metamorphic rocks, which are created by high temperatures or high pressure transforming an original rock. Foliation refers to the layering of minerals in a rock, which gives the rock a layered appearance; nonfoliated rocks do not exhibit this.Foliated. Medium to coarse grained. Foliation formed by alignment of visible crystals; rock breaks along scaly foliation surfaces; crystalline texture. Visible sparkling crystals of platy minerals (chlorite, biotite, muscovite), bladed crystals, or prismatic crystals. Parent: mudstone, shale, slate, or phyllite The various types of foliated metamorphic rocks, listed in order of the grade or intensity of metamorphism and the type of foliation are slate, phyllite, schist, and gneiss (Figure 7.8). As already noted, slate is formed from the low-grade metamorphism of shale, and has microscopic clay and mica crystals that have grown perpendicular to the stress.Metaconglomerate is a rock type which originated from conglomerate after undergoing metamorphism. Conglomerate is easily identifiable by the pebbles or larger clasts in a matrix of sand, silt, or clay. Metaconglomerate looks similar to conglomerate, although sometimes the clasts are deformed.

on the basis of texture (foliated vs. non-foliated), grain-size, and mineral composition. Texture: Metamorphic rocks may have either foliated (layered) or non-foliated texture. Foliated texture is a pervasive layering caused by compositional layering or by the parallel orientation of platy (e.g, mica) or elongate (e.g., amphibole) mineral grains.
