Metamorphic Rocks Pamela J. W. Gore Georgia Perimeter College Objectives List the agents of metamorphism and briefly describe the effects of each agent. Briefly describe the textural differences exhibited by metamorphic rocks (foliated, non-foliated). Describe the use of index minerals in the interpretation of metamorphic zones. Discuss the types of metamorphism. Discuss the relationship between metamorphism and plate tectonics. Metamorphism means "changed form". Agents of Metamorphism Changes occur because of: Heat Pressure Chemical fluids Rocks adjust to become more stable under new, higher temperatures and pressures. Heat There are several sources of heat for metamorphism. Geothermal gradient Temperature increases with depth at a rate of 20 - 30 degrees C per km in the crust. Ultimate source of the heat? Radioactive decay. Increase of temperature and pressure with depth causes Regional Metamorphism Heat may come from large bodies of molten rock rising under a wide geographic area. Intrusions of hot magma can bake rocks as it intrudes them. Lava flows can also bake rocks on the ground surface.

Rocks Rocks are all around us. They make up the backbones of hills and mountains and the foundations of plains and valleys. Beneath the soil you walk on and the deep layers of soft mud that cover the ocean basins is a basement of hard rock. What are rocks made of? Rocks are made up mostly of crystals of different kinds of minerals , or broken pieces of crystals, or broken pieces of rocks. Some rocks are made of the shells of once-living animals, or of compressed pieces of plants. Where do rocks come from? Rocks are divided into three basic types, igneous sedimentary and metamorphic , depending upon how they were formed. Plate tectonics provides an explanation for how rocks are recycled from igneous to sedimentary to metamorphic and back to igneous again. Igneous rocks Igneous rocks (from the Greek word for fire) form from when hot, molten rock (magma) crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive , depending upon where the molten rock solidifies.

Geologic Glossary This glossary contains simplified definitions for technical terms used within this site. For more complete, technical definitions, click here A B C ... Z A ablation Occurs when more glacier ice is lost by melting and evaporation each year than is added by snowfall. absolute age The approximate age of a geologic event, feature, fossil, or rock in years. 'Absolute' ages are determined by using natural radioactive 'clocks'. The preferred term is radiometric age accretion A process that adds part of one tectonic plate to a larger plate along a convergent (collisional) plate boundary. actinolite A bright to gray-green member of the amphibole mineral family. In addition to silica , it contains calcium, magnesium, and iron. Actinolite is a non-hazardous relative of asbestos and is a common mineral in metamorphic rocks. active volcano A volcano that has erupted within historical time and is likely to do so again in the future. A horizon The top layer of soil. Plant and other organic debris builds up in this layer. This is the part of the soil generally referred to as 'top soil'. alluvial fan A fan-shaped pile of sediment that forms where a rapidly flowing mountain stream enters a relatively flat valley. As water slows down, it deposits sediment (alluvium) that gradually builds a fan.

Rocks Rocks are all around us. They make up the backbones of hills and mountains and the foundations of plains and valleys. Beneath the soil you walk on and the deep layers of soft mud that cover the ocean basins is a basement of hard rock. What are rocks made of? Rocks are made up mostly of crystals of different kinds of minerals , or broken pieces of crystals, or broken pieces of rocks. Some rocks are made of the shells of once-living animals, or of compressed pieces of plants. We can learn something about the way a rock formed from by looking carefully at the evidence preserved inside. What a rock is made of, the shapes of the grains or crystals within the rock, and how the grains or crystals fit together all provide valuable clues to help us unlock the rock's history hidden within. Where do rocks come from? Rocks are divided into three basic types, igneous sedimentary and metamorphic , depending upon how they were formed. Plate tectonics provides an explanation for how rocks are recycled from igneous to sedimentary to metamorphic and back to igneous again.

Seafriends - Soil: Geology Although soil seems the end product from weathering rocks, it is merely a stage in the gigantic cycle of mineral recycling by the movement of tectonic plates. Humans use soil for their daily needs but do not sufficiently take account of its slow formation and fast loss. Discover the amazing geology of soil formation and the basic rock and soil types. tectonic mixing The tectonic movement of the crustal plates sweeps sediments onto continents and underneath them where they are molten into new rock. It is a continuous process of rejuvenating continental rock. rock formation In the cauldron of Earth, new rocks are formed, to emerge through volcanoes or by being exposed after erosion. The melting pot brings minerals together, then separates them into various classes of igneous rock. soil formation Exposed to low pressure, low temperatures and water and vegetation, rocks decompose into minerals that form soil and that feed plants. soil profile In a cross-section of soil, various zones or horizons are formed. Each has its own meaning and function. sediments By natural erosion, soil is transported towards the sea but in the process, seggregates its fine particles to form new soils and sedimentary rock.

To Guide Entry Introduction Most middle school students are not familiar with the geology of Connecticut. This unit will introduce students to the geology of Connecticut through its history, rocks, soil, and the minerals that are contained in the rocks. The purpose of the unit is to give the student some of the history of Connecticut landforms, rocks, minerals and to show how these were formed and how all this came about. Also, it is intended to give students hands on experience with geological materials and to describe a unique cultural landscape which has played an important role in the development of Connecticut which, still is an important visual element in maintaining Connecticut’s environmental character. GOAL 1. To provide experience with soils, rocks and their minerals through hands-on materials within the classroom. 2. To provide basic data through geologic mapping and research for use in science and math.

For Example, the Mexican deposits of Amethyst are lighter, while samples from Brazil can reach a deep purple color. Even though they are the same basic stone, slight variations in the chemical composition of each result in a unique crystal. Even samples from the same mine can appear quite different; it all depends on the elements that are present at the time of the crystal's development.
