Marble is found in many countries, including Belgium, France, Great Britain, Greece, India, Italy, and Spain. Gneiss sometimes is the end product of this sequence, but is often simply a ‘high-grade’ metamorphic product of granite or some other igneous rock. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. 1. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. Type of rock = foliated. High grade metamorphic rock, such as the beautiful green and red Eclogite, forms from basic Igneous rocks deep below the Earth’s mantle whilst lower grade metaphorphic rock such as Slate is formed nearer the surface. The bottom left photo (Figure 8. Slate is produced by low grade metamorphism, which is caused by relatively low temperatures and pressures. What does sedimentary limestone turn into when heat and pressure is applied? Marble, an intermediate grade metamorphic rock. Regional metamorphism is also classified into the following two types. 5. It has the same composition as the limestone from which it was formed by metamorphism. 55) show a marble that contains green forsterite (olivine). ) Metamorphic rocks formed in the shallow crust are referred to as low-grade metamorphic rocks ; those at higher temperatures and pressures as high-grade metamorphic rocks . Examples of metamorphic rocks are Marble, Slate, Granite gneiss, quartzite, and biotite schist. limestone. Slate usually has a light to dark brown streak. Typically unfoliated, granular crystalline rocks. 8). Lapis Lazuli, the famous blue gem material, is actually a metamorphic rock. Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Limestone, a sedimentary rock, will change into the metamorphic rock marble if the right conditions are met. So geologists say that shale is the parent rock. X Research source The key to identifying marble is noticing the large crystals that seem randomly distributed, since it is a non-foliated form of metamorphic rock. As the temperature and/or pressure increases on a body of rock we say that the rock undergoes prograde metamorphism or that the grade of metamorphism increases.

Marble is quarried in Vermont, Tennessee, Missouri, Georgia, and Alabama. Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth. In conclusion, marble is a metamorphic rock of great beauty, strength, and durability. Geologists map metamorphic zones based on mineral changes. From limestone. Usually, marble contains other minerals, including quartz, graphite, pyrite, and iron oxides. The surface of phyllite is typically lustrous and sometimes wrinkled. In many cases, after low-grade metamorphic changes the parent rock may still be easily distinguishable. Metamorphic Grade Metamorphic Grade refers to extent in which metamorphism can transform the the preexisting rock. Temperature and directed pressure are dominating factors. Oct 10, 2009 · Marble, the rock, is metamorphic. Low-grade metamorphism takes place at temperatures between about 200 to 320oC, and relatively low pressure. E) Metaconglomerate formed from conglomerate. Nonfoliated rocks (Table 2) are classified based on composition, and this usually depends on the type of rock it originally formed from (called the protolith). Environmental conditions can include changes in temperature, pressure, and mechanical stress, and the addition and subtraction of chemical components. Regional metamorphism: It occurs over wide areas (hundreds of kilometers) and within large Orogenic (mountain building process) belts. Metamorphic rocks can be classified into two main categories based on the way they are formed - those that are foliated as they have been formed due to high pressure and under shear stress and those that are not foliated under any form of pressure. Experiments have shown that low-grade metamorphic minerals are sta-ble at about 100°C--300°C and that common high-grade minerals are stable at about 700°C--850°C. It metamorphosed to a marble during the Grampian orogeny around 480 million years ago but crystallised very few of the metamorphic indicator minerals that George Barrow (1853—1932) used when he defined ‘Barrovian metamorphic zones' (chlorite . Non-Foliated Metamorphic Rocks Marble: a metamorphic rock composed predominantly of calcite or dolomite.
