What is the protolith of marble?

LimestoneLimestone is a protolith for marble.

What is the parent rock for a marble?

Marble

What is rock protolith?

The original rock that has undergone metamorphism is called the protolith. Protolith can be any type of rock and sometimes the changes in texture and mineralogy are so dramatic that is difficult to distinguish what the protolith was. Note that diagenesis and weathering are also a changes in form that occur in rocks.

What is protolith quizlet?

A protolith is the original, unmetamorphosed rock from which a given metamorphic rock is formed (proto-: first; lithos: rock; both Greek). For example, the protolith of a slate is a shale or mudstone.

What is the protolith of slate quizlet?

For example, the protolith of a slate is a shale or mudstone.

What is the protolith of Migmatite?

Other migmatite hypotheses

Such granites derived from sedimentary rock protoliths would be termed S-type granite, are typically potassic, sometimes containing leucite, and would be termed adamellite, granite and syenite.

Where is mylonite formed?

Mylonites form deep in the crust where temperature and pressure are high enough for the rocks to deform plastically (ductile deformation). Mylonites form in shear zones where rocks are deformed because of the very high strain rate.

How is augen gneiss formed?

Augen form in rocks which have undergone metamorphism and shearing. The core of the augen is a porphyroblast or porphyroclast of a hard, resilient mineral such as garnet. The augen grows by crystallisation of a mantle of new mineral around the porphyroblast.

What is the difference between migmatite and gneiss?

is that gneiss is (geology) a common and widely-distributed metamorphic rock having bands or veins, but not schistose while migmatite is (geology) any rock of mixed appearance, being an intimate mixture of granite and older rock, specifically from intense metamorphism which partially melts the rock, causing it to …

What is the parent rock of migmatite?

migmatite, in geology, rock composed of a metamorphic (altered) host material that is streaked or veined with granite rock; the name means “mixed rock.” Such rocks are usually gneissic (banded) and felsic rather than mafic in composition; they may occur on a regional scale in areas of high-grade metamorphism.

What is Metaconglomerate used for?

A metamorphic rock formed by recrystallization of a conglomerate. This category is also used for meta-conglomerate.

Why is the nature of the protolith so important when thinking about metamorphic rocks?

Chemical Composition of the Protolith

Therefore, not only does the protolith determine the initial chemistry of the metamorphic rock, most metamorphic rocks do not change their bulk (overall) chemical compositions very much during metamorphism.

Which of the following is the parent rock of marble quizlet?

Quartzite is made from sandstone; marble is made from limestone.

How marble is formed?

Composed largely of calcite (a form of calcium carbonate), marble is a metamorphic rock that forms when limestone is recrystallized under the influence of heat, pressure, and chemical processes beneath Earth’s surface.

What major change occurs during metamorphism of limestone to marble?

What major change occurs during metamorphism of limestone to marble? Calcite grains increase in size. Of the following rock types, which is characterized by the segregation of light- and dark-colored minerals into thin layers or bands?

What process turns limestone into marble?

Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. During metamorphism the calcite limestone recrystallizes, forming the interlocking calcite crystals that make up the marble.

Why is limestone referred to as the parent rock of marble?

Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.

What are the processes that act on limestone and changes it into marble?

Question: Question 15 (2 points) During the rock cycle, limestone (sedimentary rock) can be changed into marble (metamorphic rock). The processes that act on limestone and change it into marble are weathering and erosion heat and pressure compacting and cementing melting, cooling, and hardening.

What is the parent rock of slate *?

Slate

What type of rock is formed when rock pieces called sediments become cemented together?

sedimentary rock

14) sedimentary rock forms when sediments are compacted and cemented together, when minerals form from solutions, or when water evaporates leaving crystals behind. The sediments in sedimentary rock are often held together with natural cements. Examples of sedimentary rocks include sandstone, limestone, and rock salt.
