Only sedimentary rocks can be metamorphosed
WebAs pelitic rocks (e.g. shales and mudstones) contain many different minerals and elements, many new minerals can form when they are metamorphosed. New minerals grow at progressively higher temperatures, so pelitic rocks are the most useful in determining the metamorphic zones in contact metamorphic assemblages: WebMarble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Under the conditions of metamorphism, the calcite in the limestone ...
