- changes to rocks that take place at moderate to great depths in Earth's interior, like new textures, new mineral assemblages, or both, Vertical movement of a portion of a Earths crust to achieve balance, The stable core of continents, composed of metamorphic rocks and granitic plutons, Factors controlling the characteristics (texture and mineral content) of metamorphic rocks, 1) the composition of the parent rock before metamorphism, Why composition of parent rock before metamorphism affects character of metamorphic rock, No new elements or chemical compounds are added during metamorphism, except sometimes water, so the mineral content of the metamorphic rock depends on the chemical composition of the parent rock (no new ingredients, just what was already there and available for recrystallization), Why temperature during metamorphism affects character of metamorphic rock, Minerals are stable only at specific temperature ranges, A mineral that will not react with another substance or convert to a new mineral or substance, How pressure affects character of metamorphic rock, - new minerals that crystallize under high pressure occupy less space than the minerals they formed from because the lithostatic pressure forces atoms closer together into a more closely packed crystal structure, Pressure applied equally on all surfaces of a substance as a result of burial or submergence, The confining pressures of the earth that push upon an object deeply buried in the earth, that forces grains closer together and eliminates pore space, How tectonic forces affects character of metamorphic rocks, Differential stress and compressive stress, An object is under stress when force is applied to an object, When the forces on a body are stronger or weaker in different directions (as opposed to confining pressure where pressure is applied equally on all surfaces), How differential stress affects metamorphic rocks, - important influence on texture because it forces the constituents of the rock to become foliated (parallel to one another) due to compressive stress and shearing ass, A rock that is created by shearing during faulting (movement of bedrock along a fracture), - a rock formed from pulverized rock in a fault zone, the rock is cool and brittle due to low depth, but the pressure is sufficient to compress the pulverized rock into a compact, hard rock. They usually start out as sedimentary rocks like sandstone or shale, but then volcanic material pushes up from below and bakes the sedimentary rock into a metamorphic one. A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. • Quartzite: Formed by the metamorphism of pure quartz sandstone. The land around you, no matter where you live, is made of rock. In the diagram above magma has pushed its way into layers of limestone, quartz sandstone and shale. Serpentinite 15. Unknowable Unknowable There are called non-foliated metamorphic rocks. Slate: Slate is formed from low grade regional metamorphism of […] A blank no luster is brutal no conductor be blank shines or do you sleep little semi conductors see blank shines marble good conductor fill in the blank with the proper categories jazzmynalcozer81 is … An excellent rock for billiard table tops, floor and roofing tiles, and blackboards is: a. marble b. hornfels c. gneiss d. slate e. phyllite 45. In the diagram above magma has pushed its way into layers of limestone, quartz sandstone and shale. Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a … Answer: Contact metamorphism produces non-foliated (rocks without any cleavage ) rocks such as marble, quartzite, and hornfels. 1.SOUND TRAVEL FASTER IN MEDIUMS THAT ARE, A.VERY COLD B.ELASTIC C.MORE DENSE D.NONE, what are the tangible and intangible thing that you can share? The original clay minerals in shale alter to micas with increasing levels of heat and pressure. Why do you think it is important to give the seeds neither too much nor too little water? - if a rock is foliated it is classified based on the type of foliation, determine the type: Slate, Phyllis, Schist (type depending on combination of temp and pressure when formed), Gneiss, - very fine-grained, low grade (made with lower pressures and temperatures) metamorphic rock, - converts from slate to phyllite due to higher temperatures but still low-grade pressure, - has a schistose texture with minerals that are clearly visible to the naked eye, - has a Gneissic texture, with light and dark mineral layers or lenses, Metamorphism generated by the impact of a meteorite, - high temperature is the dominant factor in metamorphism, The zone of contact metamorphism, small and narrow usually 1 - 1000 meters wide, - metamorphism that takes place at considerable depth (more than 5 km below surface), Contact metamorphism - high temperatures in a zone of contact, nonfoliated, Low-grade to high-grade, the minerals present in a metamorphic rock show its metamorphic grade, Marble and quartzite formed under regional metamorphism, - grains of calcite or quartz will recrystallize equidimensional rather than elongate or platy, so marble and quartzite will not exhibit foliation even though during regional metamorphism they are subjected to differential stress, Recrystallization of metamorphic rock into a higher grade metamorphic rock due to increasingly greater depths (which result in increasingly greater temperatures and pressures), A rock that is partially metamorphic and partially igneous, formed from gneiss that became too hot and partial melting of the rock took place. Green Schist 11. They are produced by geological processes. Streaked out parallel to fault in darker and lighter components due to shearing, Three textures that result from foliation/the affects of differential stress, Rock splits easily along nearly flat and parallel planes which indicates that per existing, microscopic plate minerals (mica) were realigned during metamorphism, Visible minerals that are platy or needle shaped have grown essentially parallel to a plane due to differential stress, When rock became very ductile during metamorphosis and new minerals separated into distinct (light and dark) layers or lenses, How fluids affect characteristics of metamorphic rocks, - helps trigger metamorphic chemical reactions by acting as an intrarock rapid transport for ions, How time affects characteristics of metamorphic rocks, - Most metamorphic rocks are composed predominantly of silicate minerals, which are notorious for sluggish chemical reaction rates, Classification system for metamorphic rocks, Marble (from limestone or dolomite), Quartzite (from quartz), Hornfels (from shale or basalt), - If a rock is non-foliated it is classified (named) based on its composition, Coarse gained, nonfoliated metamorphic rock composed of interlocking crystals, Very fine grained, nonfoliated metamorphic rock. The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly inter-grown with each other. This book was born out of a 2014 meeting of earth science educators representing most of the universities and colleges in British Columbia, and nurtured by a widely shared frustration that many students are not thriving in our courses because textbooks have become too expensive for them to buy. Rocks are constantly modified by the action of different geological agents, such as water or wind, and by living beings. gneiss (night - dark) ____ is thought to form by partial melting and in situ crystallization of the melted portion. Write the letter of the correct answer on the blank before each numb … er,B.1. Sedimentary rock can change into metamorphic rock or into igneous rock. You've likely encountered slate on a building or an old chalkboard. Gneiss 5. Hornfels 8. Quartzite 6. Granulite 13. Batuan pembentuk litosfer Pada lithosfer terdapat tiga jenis batuan yaitu: Batuan beku Batuan sedimen Batuan metamorf Awal Mula Batuan Semua batuan pada mulanya dari magma Magma adalah benda cair, panas, pijar yang bersuhu diatas 1000˚C Lava adalah magma yang sudah muncul ke permukaan Lahar adalah lava yang bercampur dengan gas, meterial piroklastik, air, tanah tumbuhan… Host rock alteration zone is up to 2–3 m thick and is represented by hornfels and marble. The least-altered samples had ophitic and poikilophitic textures and consisted mainly of plagioclase (40–60 modal%), clinopyroxene (25–45%), Fe-Ti oxides (up to 10–15%), and locally, olivine (0–10%) and minor biotite, apatite and opaque minerals. This particular marble came from the Campbell Quarry in Texas, Maryland. Skarn. White to pi nk. It is one of the factors affectingb. It stands up better to abrasion in stair treads, floor tiles, and countertops. Phyllite 4. This large boulder has bedding still visible as dark and light bands sloping steeply down to the right. Some examples of non-foliated metamorphic rocks are marble, quartzite, and hornfels. Magma collects in layers within the foliation planes of the solid rock, and then hardens to become migmatite, Sort of the reverse of prograde metamorphism, A single mineral or combination of minerals that have been tested in laboratories to determine their stability ranges under particular pressures and temperatures, - A microscope that allows the user to focus on a tiny portion of a mineral in a rock and shoot a very narrow beam of electrons into that point in the mineral, Zoning in a mineral and how a mineral grows, - A mineral grows from the center out, adding layers of atoms as it becomes larger, If pressure and temperature both are increasing, The rock is being buried deeper while becoming hotter, If pressure and temperature are both decreasing, The rock is cooling down at the same time pressure is being reduced due to erosion at the Earth's surface.
