Non-foliated metamorphic rocks such as quartzite and marble do not display the banding or layering that are present in foliated rocks. This is because their parent rock was usually sedimentary and more pure in mineral composition than the parent rocks of foliated rocks. The metamorphic rock forms from conditions of high heat and/or pressure from depth of burial.
