PPT-Metamorphic Rocks Formation and Characteristics

Metamorphic Rocks Meta means change Greek Morph means form Greek A rock that has been changed from its original form parent rock by heat pressure and fluid activity into a new form daughter rock. Rocks 3 - Metamorphic Rocks Rocks that form when a pre - existing rock ( protolith ) changes due to temperature or pressure, and/or as a result of squashing or shearing. Protolith – the pre - e 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. . Metamorphism. Metamorphic rocks: appear to have changed in their structure or chemical composition since their creation or formation.. Originally sedimentary or igneous. Altered by heat, pressure, or exposure to hot fluids in earth’s crust. GLY 2010 - Summer 2016 - Lecture 11. 2. Metamorphism. The mineralogical, chemical, and structural adjustment of solid rocks to physical and chemical conditions. 3. Metamorphic Rock. Any rock derived from pre-existing rocks by mineralogical, chemical, and/or structural changes, essentially in the solid state . LOWER-GRADE REGIONAL METAMORPHICS. Slate, Phyllite, . “Greenstone” and Schist. 2. Metamorphic Rock Definition. A sedimentary, igneous, or previously existing metamorphic rock which has undergone textural, structural, and/or mineralogical changes due to the action of one or more agents of metamorphism. CONTACT AND DYNAMIC METAMORPHIC ROCKS. Hornfels, Skarns, Talc-Tremolite Schist, and Epidosite. 2. Contact and Dynamic Metamorphism. The rocks in this lab are formed either by contact metamorphism or by dynamic metamorphism associated with movement along a fault. Metamorphism. :. . the process that creates metamorphic rocks. .. .
