Bituminous Coal c.) Chlorite, mica, quartz, feldspar, amphibole, garnet, and pyroxene. 1. The quiz will help you determine how many igneous rocks you should try to identify. Heat from the intrusion of a dike or sill or flow can bake the adjoining rocks in a contact metamorphic zone. State the name of Rock B. Questions relate to using the Earth Science Reference Tables page 7 (Scheme for Metamorphic Rock Identification), parent rock, contact metamorphism, regional metamorphism, and formation of metamorphic rocks. Pressure from the weight of overlying rocks or from stresses of mountain building rearranges the minerals in rocks into bands or rearranges the atoms of the minerals into new minerals. parent rock from which I was created was most likely. The mineral composition of the rock can be determined based on observations with a hand lens and if needed, physical or chemical tests. lookup, Linking Asteroids and Meteorites through Reflectance, Metamorphic Rocks - Washingtonville Central School District, Metamorphic Rock Notes, Chapter 6.2, pages 133, “changed rocks” – can form from: sedimentary, igneous or other, the index minerals and mineral assemblages, petrographic report on two diamond drill core samples from the. Foliated texture is further subdivided based on the presence or absence of pronounced color banding in the rock. Read the descriptions in your lab manual or textbook for the source rock of each of the metamorphic rocks that you identify. The amount of time, amount of pressure, and highness of temperature determine what types of metamorphic rocks are made. Set 2 — Scheme for Metamorphic Rock Identification Which rock forms by the recrystallization of unmelted rock material under conditions of high temperature and pressure?

FOLIATED rocks: mineral grains have clear preferred orientation INCREASING METAMORPHISM METAMORPHIC ROCK PROTOLITH slate shale/mudstone phyllite varies; usually pelite schist varies; often pelite gneiss varies; sandstone or granite 2. There are two main types of metamorphism. Using your senses and the Scheme for Metamorphic Rock Identification, you will be able to first classify and identify the rocks and their environments of formation. This chart is arranged into columns and You need to know this number, because you need to know how many of the rocks that you are working with are Igneous Rocks. Many are downloadable. Answer the following questions based on your interpretation of the Scheme for Metamorphic Rock Identification chart of the Earth Science Reference Tables (page 7) as well as your class notes. wikipedia, FOLIATED rocks: mineral grains have clear preferred orientation . 0/1 e 2009 Scheme for Sedimentary Rock Identification Indicate in the name(s) of the probable parent rock(s) in the last column of the metamorphic rock identification form. lookup, Age of the Earth lookup, Marine geology of the Cape Peninsula and False Bay lookup, Clastic rock Nonfoliated textures are further described on the basis of the grain (crystal) size in the rock. PROCEDURE First, take some time to familiarize yourself with the flow of the identification chart. Metamorphism also happens when rocks are buried deeply during the process of mountain building. Metamorphic Rocks Metamorphic rocks form when existing rocks are exposed to intense heat and/or pressure inside the earth These intense conditions will alter the rocks, changing (morphing or recrystallizing) them into a new rock. wikipedia, When you split a mineral into pieces, you still have pieces of the same mineral. The kind of metamorphic rock made depends on the kind of original rock; for exampl… lookup, Weathering Scheme for Metamorphic Rock Identification GRAIN TYPE OF TEXTURE SIZE COMPOSITION METAMORPHISM COMMENTS ROCK … Rocks can be a mixture of different kinds of minerals, a mixture of many grains of the same kind of mineral, or a mixture of different grains of rocks. wikipedia, TEXTURE GRAIN medium Medium Fine Fine Fine coarse Scheme for Metamorphic Rock Identification MAP SYMBOL TYPE OF COMPOSITION METAMORPHISM COMMENTS Low-g rade metamorphism of shale Foliation surfaces shiny from microscopic mica cry stals .

Metamorphic rocks (changed rocks) are made when existing rocks are subjected to high temperatures and high pressures for long periods of time. View Rock Identification PPTs online, safely and virus-free! For example, when you break granite apart, you get small pieces of quartz (clear), feldspar (pink or white), and mica (black). NONFOLIATED rocks (granoblastic): little or no preferred mineral I. NCREASING METAMORPHISM METAMORPHIC ROCK PROTOLITH slate shale/mudstone phyllite varies; usually pelite schist varies; often pelite gneiss varies; sandstone or granite 2. wikipedia, Once the texture and mineral composition of the rock has been determined, turn to the metamorphic rock determination chart that follows to determine the basic name of the rock. Scheme for Metamorphic Rock Identification MAP SYMBOL TYPE OF COMPOSITION METAMORPHISM COMMENTS Low-g rade metamorphism of shale Foliation surfaces shiny from microscopic mica cry stals Platy mica crystals visible from metamorphism of clay or feldspars High-grade metamorphism; mineral types segregated into bands Metamorphism of bituminous coal "Meta" means change and "morph" means form, thus metamorphic rocks are rocks that have changed form. Metamorphism (meta = change, morph = form) happens when molten rock intrudes other rocks and bakes the contact zone where the molten rock touches the preexisting rock. Remember, if you know the rock, you know the past environment! The Scheme for Igneous Rock Identification diagram from the New York State Earth Science Reference Tables. Description: Using your senses and the Scheme for Metamorphic Rock Identification, you will be able to first classify and identify the rocks and their environments of formation. The protolith, or. This is a continuation of lesson 1.10, in that it similarly examines the 'Scheme for Metamorphic Rock Identification' on page 7 of the ESRT (attached). When you split a rock into very small pieces, the pieces are different from each other. Smooth, flat surfaces, from slatey cleavage, Satin sheen to rock rather than individual flakes. Scheme for Metamorphic Rock Identification. Metamorphic rocks (changed rocks) are made when existing rocks are subjected to high temperatures and high pressures for long periods of time. wikipedia, Heat from the intrusion of a large igneous mass can metamorphose a large area. For example, if you have rocks that look like … wikipedia, a. sandstone b. limestone c. shale d. dolostone. According to the Scheme for Metamorphic Rock Identification, if sufficient heat and pressure occurred what kind of metamorphic rock might form from: a.) Metamorphic rocks are identified based on grain size, mineral composition, and texture (see the accompanying chart). of Presentation Mode Download. There are two major textural groups in metamorphic rocks: Foliated and Non-Foliated. Physical Geology, Adapted by Anne Huth, Pima Community College. Texture Texture Composition Type of Metamorphism Comment Rock Name Mica Regional (Heat and Pressure increase w/ depth) Low-Grade metamorphism of SHALE Mica, Quartz, Feldspar, Amphiboles, Garnet Regional (Heat and Pressure increase w/ depth) Foliation surfaces shiny from microscopic mica crystals Mica, Quartz, Feldspar, Amphiboles, Garnet, … on page 702 of the textbook to answer the questions below. Texture is shown along the left side of the key. 16. Scheme for Sedimentary Rock Identification INORGANIC LAND-DERIVED SEDIMENTARY ROCKS TEXTURE GRAIN SIZE COMPOSITION Pebbles, cobbles, and/or boulders embedded in sand, silt, and/or clay Clastic (fragmental) COMMENTS Rounded fragments Mostly quartz, feldspar, and clay minerals; may contain fragments of other rocks and minerals Sand (0.006 to 0.2 cm) Silt (0.0004 to 0.006 cm) Clay … METAMORPHIC ROCK … 17. State the name of Rock A. In this assignment, you will classify metamorphic rocks based on their texture and composition as well as determine their corresponding protolith using the classification scheme provided in Table 2 for Metamorphic Rocks Background Information. All metamorphic rocks are derived by the action of heat and/or pressure on pre-existing igneous, sedimentary, or metamorphic rocks.
