PPT-METAMORPHIC ROCKS

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. Change is Good. Metamorphic Rocks. Formed from intense heat and pressure!. Sources of Heat. 300-1400 degree Celsius temperatures are needed for Metamorphism.. Sources of heat include:. Magma or lava. 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. HIGHER-GRADE REGIONAL METAMORPHICS. Gneiss and Eclogite. 2. High-Grade Regional Metamorphic Facies. Rocks in this laboratory represent high to very high grade regional metamorphic rock. Facies represented are the amphibiolite, granulite, and eclogite facies. 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. HIGHER-GRADE REGIONAL METAMORPHICS. Gneiss and Eclogite. 2. High-Grade Regional Metamorphic Facies. Rocks in this laboratory represent high to very high grade regional metamorphic rock.

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. There are three different types of rocks . Igneous ,metamorphic , . sedimentry. . I will tell you . information about them. . . Info on the rocks . The igneous rock. The igneous rock can be found in different colours. The igneous rock is formed when magma cools and solidifies, it may do this above . 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. S6E5. . Students will investigate the scientific view of how the earth’s surface is formed.. c. Classify rocks by their process of formation. . . Which of these BEST describes the concept of the rock cycle?.

Causes of Metamorphism. Elevated T & P. Fluids (H2O, CO2, CH4, etc.). Directed Stress. Types of Metamorphism. Regional: occur along convergent plate boundaries.. Contact: occurs along margin of a magma intrusion.. Metamorphic ROCKS. Geo 281: geology for engineers. Geology and Geophysics Department. King Saud University. What is metamorphism.
