Which of the following metamorphic rocks could have a parent rock of shale quizlet?
Which of the following metamorphic rocks could have a parent rock (protolith) of shale? Depending on the degree of metamorphism shale is subjected to it can be metamorphosed into slate, phyllite, schist, and gneiss.
Slate has abundant, coarse-grained mica. Slate forms from shales and mudstones. In slate, rock cleavage is common.
Slate and schist are both derived by metamorphism of shales and mudstones. Three major factors involved in metamorphism are elevated temperature, elevated pressure, and the chemical action of hot fluids. The distinctive layers or bands of different minerals in gneisses may be complexly folded.
There are 3 main agents that cause metamorphism. Factors that cause an increase in Temperature, Pressure, and Chemical changes are the three agents that we are going to study. Temperature increases can be caused by layers of sediments being buried deeper and deeper under the surface of the Earth.
|Miscellaneous||Foliation surface is dull and planar; Slaty Cleavage|
|Metamorphic Grade||Low Grade (Low P – Low T)|
|Parent Rock||Shale or Mudstone|
Which statement describes the formation of metamorphic rocks? Rocks beneath the surface are forced toward the mantle.
slate, fine-grained, clayey metamorphic rock that cleaves, or splits, readily into thin slabs having great tensile strength and durability; some other rocks that occur in thin beds are improperly called slate because they can be used for roofing and similar purposes.
The physical properties of slate comprise hardness and abrasion, fissility, density and porosity, thermal conductivity and thermal expansion as well as hydric and hygric properties.
Slate is a metamorphic rock of sedimentary origin. Is mainly composed of quartz, sericite and minerals of the chlorite group.
Shale has quite a dull look whereas slate shines and looks silky in the sun. Moving on, when treated with water, shale will give you an odour like clay but slate will usually not have any noticeable odour. In some cases however, it may smell like clay but have a very weak odour.
What is the main difference between slate phyllite and schist?
Phyllite has fine-grained mica flakes, whereas slate has extremely fine mica flakes, and schist has large mica flakes, all mica flakes of which have achieved a preferred orientation. Among foliated metamorphic rocks, it represents a gradation in the degree of metamorphism between slate and schist.
Unlike slate and phyllite, which typically only form from mudrock, schist, and especially gneiss, can form from a variety of parent rocks, including mudrock, sandstone, conglomerate, and a range of both volcanic and intrusive igneous rocks.
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
What are the agents that change rocks through metamorphism? The agents of agents of metamorphism are heat, pressure, and hydrothermal solution.
Temperature and pressure. Temperature and pressure are important factors in determining the new minerals that form in a metamorphic rock. Different minerals form under different pressure and temperature conditions.

Slate is considered to be in between 2.5 to 4 on this scale in terms of hardness, which means that it is, on average, almost as hard as marble and limestone, but not as hard as granite or natural quartz.
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock.
Increased heat and pressure will change the sedimentary rock into metamorphic rock. A sedimentary rock along a plate boundary is forced below another plate during subduction.
Which example best illustrates a method to show differences among Earth's layers? - Carson models how the continental crust varies in thickness.
Which best describes the next step in the formation of metamorphic rocks Brainly?
Which best describes the next step in the formation of metamorphic rocks? - Buried rocks melt deep within the mantle.
Slate is formed by a metamorphosis of clay, shale and volcanic ash that results to a fine-grained foliated rock, resulting in unique slate textures. It is a metamorphic rock, being the finest grained foliated of its kind.
While slate is a very hard flooring material, it is also quite brittle, so if something heavy is dropped on it, the tile is likely to break. Because slate is such a hard flooring material, it can be painful to stand on for long periods of time.
Slate is an excellent backsplash material since it resists heat and burning. It is also used for countertops, flooring and sometimes as an outdoor surface for walkways or driveways.
Slate is mostly made of clay but the clay can change to mica under extreme degrees of pressure. The color of slate is largely determined by the amount of iron it contains, but it is normally a shade of grey. Slate normally forms in basins between convergent plate boundaries.
Slate has many uses such as snooker tables, roofing, gravestones, flooring and garden decorations.
Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. It is popular for a wide variety of uses such as roofing, flooring, and flagging because of its durability and attractive appearance.
Slate is a fine-grained, homogeneous metamorphic rock, which is foliated (in geology: consisting of layers, layered). It comes mainly in a great variety of grey but can also be purple, green or cyan. It is mainly quarried in Spain and Brazil but is also quite commonly found in the USA and in Britain and Asia.
Slate is a metamorphic rock with a dull luster. The most common color of slate is gray, but it can also be brown, green, purple, or blue. Slate is formed when a sedimentary rock (shale, mudstone, or basalt) is compressed. Over time, slate may transition into other metamorphic rocks, such as phyllite or schist.
What is the difference in mineral composition between shale and slate? Shale (sedimentary) is made predominately of The Clays. Slate (metamorphic) is made predominately of The Micas.
What type of rock is shale?
Shale rocks are those that are made of clay-sized particles and are have a laminated appearance. They are a type of sedimentary rock. Shale is the abundant rock found on Earth. They are usually found in areas where gentle waters have deposited sediments that become compacted together.
Phyllite has fine-grained mica flakes in a preferred orientation, whereas slate has extremely fine clay flakes that achieve a preferred orientation, and schist has large flakes in a preferred orientation. Among foliated metamorphic rocks, it represents a gradation in the degree of metamorphism between slate and schist.

Both slate and phyllite are formed in similar ways, phyllite, however, is subjected to even higher temperatures and greater pressures than slate, which causes the clay within the material to break down and form mica. The mica in phyllite are larger than in slate and are visible as a sheen on the material's surface.
Slate forms in low-grade metamorphic environments from a parent rock of either shale, mudstone, or siltstone.
Answer: Metamorphism alteration of the composition or structure of a rock by heat, pressure, or other natural agent. Marble and slate are examples of metamorphic rock.
Which of the following features is associated with metamorphic rocks? Foliation.
Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.
Metamorphism can be caused by burial, tectonic stress, heating by magma, or alteration by fluids. At advanced stages of metamorphism, it is common for a metamorphic rock to develop such a different set of minerals and such a thoroughly changed texture that it is difficult to recognize what the protolith was.
Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions.
What is the name of this metamorphic rock quizlet?
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) Under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals.
Parent Rock. Limestone or Dolostone. Metamorphic Environment. Variable grade regional or contact metamorphism along a convergent plate boundary.
Quartzite is made from sandstone; marble is made from limestone.
The Correct is Gneiss. Gneiss usually forms by regional metamorphism at convergent plate boundaries.
