Metamorphic Rock
Metamorphism means to change form; this is exactly what metamorphic rocks do. This paper will take a look at the Earth’s rock cycle to examine exactly where the metamorphic rock fits into it. It will also look at how metamorphic rocks are formed and the relationship between metamorphic rocks and igneous rock and sedimentary rocks. This paper will examine the geological characteristics and materials of metamorphic rocks, and examine some examples of metamorphic rocks and will describe mineral composition of some examples and explain its economic uses.
The Rock Cycle The rock cycle helps people to understand the starting point of the igneous, sedimentary, and metamorphic rocks. In addition to explaining how each of the …show more content…
Slate is black when it contains organic materials, it is red when it contains iron oxides, and it is green when it has chlorite. Slate can form shale or sometimes even volcanic ash. Slate can be found all over but is most commonly found in Britain. It is used in consumer products like pool tables, chalkboards, and roofing tiles.
Another example of a very common metamorphic rock seen quite frequently is marble. Marble is used as a common building material in things from tiles and countertops, to statues and other carved arts. Marble is made up of calcite crystals formed from smaller re-crystallized rocks usually containing limestone and dolostone. Limestone is where the marble receives its color so marble can come in almost any color. Marble is mostly found in Canada, Italy, Germany, Spain, India, the United States and China.
Geological Characteristics and Materials of Metamorphic Rock
Metamorphic rock takes on several characteristics after formation. The most noticeable characteristic is foliation. This is the banding that occurs during metamorphism. The banding arrangement varies from fine to coarse crystalline structures. The banding can be uniform as seen in slate or discontinuous as found in Gneiss. Rocks with no apparent orientation are called nonfoliated. This characteristic of metamorphic rock generally consists of a single mineral of larger interlocking crystals (Tarbuck, Lutgens, & Tasa, 2006). Marble is an

Metamorphic Rock

Thirsty Rocks Out of 15 different types of rocks, which rock will absorb the most mineral oil and increase the most in mass? To understand this experiment, it is important to know a few key facts. Obsidian, granite, basalt, scoria, and rhyolite are igneous rocks. Shale, calcareous tufa, sandstone, conglomerate, and limestone are sedimentary rocks. Slate, marble, quartzite, gneiss, and shist are all metamorphic rocks. The porosity of a rock is the measure of the rock's ability to store a fluid.…

My final exam Essay

Rocks In nature, there are 3 types of rocks: metamorphic, igneous, and sedimentary. Metamorphic rocks form when heat and/or pressure are applied to another rock. An igneous rock is a rock that is formed by cooling magma. Finally, a sedimentary rock is formed when other rocks are weathered down by rocks and water and the particles that come off them as a result of this are compacted and cemented together to form a new rock. A mineral can form in two different ways: it can crystallize from cooling…

Science DBQ: Igneous Rocks

DBQ The rock cycle is a very important type of geology, and is important to scientists. The rock cycle is a series of changes that transform one rock into another (OI). The rock cycle has no starting point (Doc.1). The igneous rock goes through weathering and erosion, which leads to sediment. Then, the sediment is pressed together and cemented, which leads to sedimentary rock. The sedimentary rock is changed by heat and pressure, which leads to a metamorphic rock. Then, the metamorphic rock starts…

landscape that is currently glaciated. A glacier is a large body of continuously accumulating ice and compacted snow. The foundation of Yosemite National Park's conservation is the icy setting that resulted from the relations of the primary rocks (underlying rocks) with the glaciers. Furthermore, Yosemite National Park is located in the Sierra Nevada mountain range. As a whole, the Sierra Nevada is a lopsided mountain range with a lengthy, soft slant on its west side and a not so lengthy, sharply sloped…

Chemistry Rock Cycle Essay

THE ROCK CYCLE BY EDWARD SALMON - SMITH Types of rock. There are three types of rocks. Sedimentary, for example chalk, limestone, sandstone and shale. Igneous, for example basalt and granite. Finally, Metamorphic, for example slate and marble. What is the rock cycle? The Earth's rocks do not stay the same forever. They are continually changing because of processes such as weathering and large earth movements. The rocks are gradually recycled over millions of years. This is called the rock cycle…

Oldest Layer Of Marble

Technical Report The oldest layer is marble which is a metamorphic rock. Over the course of many years, sediment are deposited to form a layer of sedimentary rock. However, an event such as an igneous intrusion or the presence of a batholith can transform that sedimentary rock into metamorphic rock. Marble is a non foliated metamorphic rock which mean it is created through contact metamorphism on the parts that the igneous intrusion is touching the marble, but rest of layer of the marble is created…

Rock the House. Although New York City is known around the world for its manmade wonders, a question that one asks themselves is how Manhattan came to be, and the answer is Bedrock. Bedrock is a solid rock below the loose surface of a material. It's a solid rock that makes up the earth's crust, it's found underneath surface deposits of soil. It is the solid rock beneath loose deposits like soil or alluvium, and is usually unweathered. Their are also three processes by which bedrock is formed. Igneous…
