FAQ: What Is The Protolith Of Marble Quizlet?

What is the protolith of a marble?

marble—marble is a metamorphic rock made up almost entirely of either calcite or dolomite, for which the protolith was either limestone or dolostone, respectively. Such marble is often used as decorative stone in buildings.

What is the name of the type of foliation that is defined by the preferred orientation of large mica flakes as shown in the photo looking down on the foliation plane )?

Is a medium to to coarse-grained metamorphic rock containing a type of foliation called schistosity. -This fabric is defined by the preferred orientation of large mica flakes (typically muscovite and/or biotite).

What type of foliation does slate a common material used for roof shingles?

It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called ” slaty cleavage”.

What is the highest quality marble?

Calacatta marble is considered as the most luxurious marble type due to its rarity. Calacatta stone is very often mistaken for Carrara marble due to the striking similarities in colour and veining.

Which country has the best marble?

While marble is quarried in many countries around the world including Greece, USA, India, Spain, Romania, China, Sweden and even Germany, there is one country which is generally considered the home of the most high-grade and luxurious marble available – Italy.

What type of rock is marble?

Marble. When limestone, a sedimentary rock, gets buried deep in the earth for millions of years, the heat and pressure can change it into a metamorphic rock called marble. Marble is strong and can be polished to a beautiful luster. It is widely used for buildings and statues.

What is meant by foliation?

Foliation, planar arrangement of structural or textural features in any rock type but particularly that resulting from the alignment of constituent mineral grains of a metamorphic rock of the regional variety along straight or wavy planes.

How do you identify phyllites?

The alignment of the mica grains gives phyllite a reflective sheen that distinguishes it from slate, its metamorphic precursor or protolith. Phyllite is usually gray, black, or greenish in color and often weathers to a tan or brown. Its reflective sheen often gives it a silvery, nonmetallic appearance.

What type of rock is granite?

Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss.

What kind of rock is formed by the process of Lithification?

Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.

How is marble formed and what type of rock is it?

Marble forms when a pre-existing limestone rock is heated to such extreme temperatures that the minerals grow larger and fuse together. The dark, foliated bands cutting through the marble are a different kind of metamorphic rock, such as slate.

Is marble a sedimentary rock?

The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Marble is usually light colored and is composed of crystals of calcite locked together like pieces of a jigsaw puzzle.

Where does black slate come from?

There is also a number of slate producing quarries in the Blaenau Ffestiniog area. The slate mines in the Llangollen area are known to produce a darker colored slate, making them almost black. In North America, slate was first quarried in 1734 along the borders of Pennsylvania and Maryland, USA.
