Discover the Marvels of Metamorphic Rocks

Learn how metamorphism transforms rocks with temperature and pressure, from regional to contact metamorphism, resulting in unique characteristics like foliation or non-foliation. Explore the composition changes and diverse types of metamorphic rocks.

  1. Metamorphic Rocks www.assignmentpoint.com

  2. METAMORPHIC ROCKS • Metamorphism means to change. • Rocks change with temperature and pressure. • Usually takes place deep in the Earth www.assignmentpoint.com

  3. Contact Metamorphism– Rocks are heated by nearby magma (affects a small scale) • Increased temperature changes the composition of the rock, old minerals are changed into new ones Hornfel is a fine-grained non-foliated metamorphic rock produced by contact metamorphism www.assignmentpoint.com

  4. Regional metamorphism: affects a large area and results from plate tectonics • Rocks are changed due to pressure www.assignmentpoint.com

  5. Metamorphic rocks can be foliated, i.e. showing layers/bands of minerals e.g. Gneiss or non- foliated e.g. Marble A. Gneiss B. Marble www.assignmentpoint.com

  6. CHARACTERISTICS OF METAMORPHIC ROCKS • May be foliated/banded • Rarely contain fossils • React with acids www.assignmentpoint.com
