Metamorphic ROCKS Geo 281 geology for engineers Geology and Geophysics Department King Saud University What is metamorphism Metamorphism is the transformation of one rock type into another. Metamorphic Rocks . Are Composed of Sedimentary, Igneous, or Metamorphic Minerals that Have Recrystallized.. Marble from Carrara, Italy. Pre-existing sedimentary, igneous, or metamorphic rock changed to a new assemblage of minerals. . Planet Earth. Unit 5 . Topic 1 - Minerals. Minerals. Rocks contain naturally . occurring, . non-living . minerals. Most . minerals are rare and can be . elements.  (. pure substances. ) or.  . compounds . UNIT . - . 6. What is Metamorphism. Metamorphism. (from the Greek words for “changing form”) is the process by which rising temperature and changes in other environmental conditions transform rocks and minerals. Granite, Alkali Feldspar Granite, Granodiorite, Quartz Monzonite, and Monzonite. 2. IUGS Intrusive Igneous Rock Chart . 3. “Granite”. Rocks in this lab are plutonic. They formed by very slow cooling and show corresponding large crystals. Rocks are classified by how they are formed, their composition, and texture. Rocks change over time through the rock cycle.
