Quizplus · Accepted Answer

Quartzite and marble are both metamorphic rocks that lack foliation due to the absence of the alignment of minerals or banding. Quartzite is formed from sandstone and marble is formed from limestone or dolostone. Both rocks are typically composed of a single mineral or a few minerals, which do not align during the metamorphic process.
