• Restate how metamorphic rocks relate to the two other rock groups (sedimentary and igneous). Introduction to Rocks. granite. The fabric can be either a planar fabric, called “foliation”, or a linear fabric, called “lineation”. again tectonic. subduction. Metamorphic rocks are formed from existing sedimentary rocks that are changed because of heat or pressure Earth movements may cause rocks to be deeply buried or ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 7f7e02-NWExY Rocks have many different parts . zones. The Rock Cycle. forces at areas known as . A. Schistosity formed by muscovite and biotite. Silicate structure. Rocks can be sorted into groups by looking at their parts. Metamorphic Rocks Presentation - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. Geology of Rocks. Foliated Metamorphic Rocks. By this definition schist is a broad term, and slates and phyllites are also types of schists. Free Presentations in PowerPoint format. In geology, rocks and stones are naturally occurring, solid aggregate chunks of one or more minerals. ... Metamorphic Rocks. Parts Of Rocks. -TEXTURE=sizes, shapes and positions of grains in the rocks TYPES OF ROCKS THE COMPOSITION OF ROCKS IS DETERMINED -BY THE KIND OF MINERALS & -THE AMOUNT MINERALS THAT MAKE IT UP TYPES OF ROCKS 3 TYPES OF ROCKS IGNEOUS SEDIMENTARY METAMORPHIC FORMED WHEN MAGMA or LAVA COOLS AND HARDENS (SOLIDIFIES) 2 TYPES INTRUSIVE … Metamorphic Rock. figure will be added pending permission . Some rock parts are: The Rock Cycle. Any of the rock types can eventually be returned to Earth's interior by . rocks. In common usage, schists are restricted to those metamorphic rocks in which the foliated minerals are coarse enough to see easily in hand specimen. Rocks from Volcanic Sources. • Recognize the different types of … Metamorphic rocks and processes • Metamorphism comes from the Greek words “Meta” - change “Morphe” - form • Metamorphic rocks form by solid-state (no melting) transformation of preexisting rock by processes that take place beneath Earth’s surface. Figure 9 – 4. Metamorphic rocks are made from other rocks. Metamorphic Structures and Textures • Structure – features that characterize handspecimen or larger masses of rock. • Texture – microscopic to small-scale mesoscopic features of the rock produced by: 1. Regional and contact metamorphism. Schist: a metamorphic rock exhibiting a schistosity. The three main types, or classes, of rocks include sedimentary, metamorphic and igneous. Grain sizes 3. Grain distributions 5. Most of the most common rocks in the crust are silicates. conglomerate. • Describe how metamorphic rocks are produced by the action of heat, pressure, and fluids on preexisting parent rocks over the course of time. Grain shapes 2. Once in Earth's interior, extreme pressures and temperatures melt the rock back into magma to begin the . Grain orientations 4. Igneous Rocks. metaconglomerate. metamorphic. rock cycle. Typically metamorphic rocks develop some kind of metamorphic fabric during the metamorphic event(s). gneiss. Metamorphic rock fabrics. Heat and pressure help change an igneous or sedimentary rock into a new kind of rock (think about how a caterpillar becomes a butterfly) The Rock Cycle. 24 A thorough presentation on characteristics and description of all main types of metamorphic rocks.
