Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type. 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. 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. Cordierite Hornfels . a. quartzite2. They are produced by geological processes. In the diagram above magma has pushed its way into layers of limestone, quartz sandstone and shale. Shell marble, merupakan batuan marmer yang terdiri dari fosil- fosil. A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. 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. This large boulder has bedding still visible as dark and light bands sloping steeply down to the right. You've likely encountered slate on a building or an old chalkboard. Marble is metamorphosed limestone. Slate is composed mainly of clay minerals or micas, depending upon the degree of metamorphism to which it has been subjected. Help the community by sharing what you know. Hornfels rocks are metamorphic rocks. Over time, slate may transition into other metamorphic rocks, such as phyllite or schist.

Lherzoloite 16. Sedimentary rock can change into metamorphic rock or into igneous rock. Granulite 13. Hydrothermal activity at divergent plate boundaries, - hydrothermal processes are important at mid-oceanic ridges, - a submarine hot spring through which very hot water returns to the ocean, - water can get carried down deep into the crust at convergent boundaries as plates with water trapped in it (sedimentary rock or oceanic crust) are subducted. - 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. THREE AGENTS OF METAMORPHISM AND THEIR EFFECTS. Quartzite, with a Mohs hardness of seven along with greater toughness, is superior to both in many uses. It is the main factor of contactf. Foliated metamorphic rocks such as gneiss, phyllite, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Might have dark streaks. 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. Hornfels 8. Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a … Start studying Earth Science MidTerm Review. The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly inter-grown with each other.

Slate 2. - 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. Three things contribute in varying proportions to the transformation from a protolith to a metamorphic rock: heat, pressure, and fluids (mostly water with dissolved ions). The rock also has a strong slaty foliation, which is horizontal in this view, and has developed because the rock was being squeezed during metamorphism. Why do you think it is important to give the seeds neither too much nor too little water? Breccia marble, merupakan batuan marmer yang mempunyai tekstur asar dan juga paesegi.
