Non-foliated rocks form when pressure is uniform, or near the surface where pressure is very low. An example of this transformation can be seen with granite, an igneous rock. Even if formed under directed pressure, quartzite is generally not foliated because quartz crystals do not normally align with the directional pressure. Non-foliated metamorphic rocks form at low pressures but high temperatures, while foliated metamorphic rocks form at high pressures. They can also form when the parent rock consists of blocky minerals such as quartz and calcite, in which individual crystals do not align because they aren't longer in any one dimension. Foliated metamorphic rocks exhibit layers or stripes caused by the elongation and alignment of minerals in the rock as it undergoes metamorphism. As a result of this process, marble can be found in massive seams in many parts of the world. Sometimes the bands are very obvious and continuous (Figure 10.17, upper right), but sometimes they are more like lenses (upper left).
